Summary:
NFC = [[ https://llvm.org/docs/Lexicon.html#nfc | Non functional change ]]
This commit is the result of modernizing the LLDB codebase by using
`nullptr` instread of `0` or `NULL`. See
https://clang.llvm.org/extra/clang-tidy/checks/modernize-use-nullptr.html
for more information.
This is the command I ran and I to fix and format the code base:
```
run-clang-tidy.py \
-header-filter='.*' \
-checks='-*,modernize-use-nullptr' \
-fix ~/dev/llvm-project/lldb/.* \
-format \
-style LLVM \
-p ~/llvm-builds/debug-ninja-gcc
```
NOTE: There were also changes to `llvm/utils/unittest` but I did not
include them because I felt that maybe this library shall be updated in
isolation somehow.
NOTE: I know this is a rather large commit but it is a nobrainer in most
parts.

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

This patch removes the comments following the header includes. They were
added after running IWYU over the LLDB codebase. However they add little
value, are often outdates and burdensome to maintain.

This patch removes the logic for resolving paths out of FileSpec and
updates call sites to rely on the FileSystem class instead.

There were some calls left to Exists() on non-darwin platforms (Windows,
Linux and FreeBSD) that weren't yet updated to use the FileSystem.

Summary:
This has multiple advantages:
- we need only one function argument/instance variable instead of three
- no need to default initialize variables
- no custom parsing code
- VersionTuple has comparison operators, which makes version comparisons much
simpler

This is intended as a clean up after the big clang-format commit
(r280751), which unfortunately resulted in many of the comment
paragraphs in LLDB being very hard to read.
FYI, the script I used was:
import textwrap
import commands
import os
import sys
import re
tmp = "%s.tmp"%sys.argv[1]
out = open(tmp, "w+")
with open(sys.argv[1], "r") as f:
header = ""
text = ""
comment = re.compile(r'^( *//) ([^ ].*)$')
special = re.compile(r'^((([A-Z]+[: ])|([0-9]+ )).*)|(.*;)$')
for line in f:
match = comment.match(line)
if match and not special.match(match.group(2)):
# skip intentionally short comments.
if not text and len(match.group(2)) < 40:
out.write(line)
continue
if text:
text += " " + match.group(2)
else:
header = match.group(1)
text = match.group(2)
continue
if text:
filled = textwrap.wrap(text, width=(78-len(header)),
break_long_words=False)
for l in filled:
out.write(header+" "+l+'\n')
text = ""
out.write(line)
os.rename(tmp, sys.argv[1])

Fix the Linux plugin lookup path to include appropriate libdir suffix
for the system. To accomplish this, store the value of
LLVM_LIBDIR_SUFFIX in lldb/Host/Config.h as LLDB_LIBDIR_SUFFIX,
and use this variable when defining the plugin path.

Summary:
It defined a couple of types (condition_t) which we don't use anymore,
as we have c++11 goodies now. I remove these definitions.
Also it unnecessarily included a couple of headers which weren't
necessary for it's operation. I remove these, and place the includes in
the relevant files (usually .cpp, usually in Host code) which use them.
This allows us to reduce namespace pollution in most of the lldb files
which don't need the OS-specific definitions.

Summary:
The std::call_once implementation in libstdc++ has problems on few systems: NetBSD, OpenBSD and Linux PPC. LLVM ships with a homegrown implementation llvm::call_once to help on these platforms.
This change is required in the NetBSD LLDB port. std::call_once with libstdc++ results with crashing the debugger.

*** to conform to clang-format’s LLVM style. This kind of mass change has
*** two obvious implications:
Firstly, merging this particular commit into a downstream fork may be a huge
effort. Alternatively, it may be worth merging all changes up to this commit,
performing the same reformatting operation locally, and then discarding the
merge for this particular commit. The commands used to accomplish this
reformatting were as follows (with current working directory as the root of
the repository):
find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} +
find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ;
The version of clang-format used was 3.9.0, and autopep8 was 1.2.4.
Secondly, “blame” style tools will generally point to this commit instead of
a meaningful prior commit. There are alternatives available that will attempt
to look through this change and find the appropriate prior commit. YMMV.

* ArchSpec::MergeFrom() would erroneously promote an unspecified
unknown to a specified unknown when both the ArchSpec and the merged
in ArchSpec were both unspecified unknowns. This no longer happens,
which fixes issues with global module cache lookup in some
situations.
* Added ArchSpec::DumpTriple(Stream&) that now properly prints
unspecified unknowns as '*' and specified unknows as 'unknown'.
This makes it trivial to tell the difference between the two.
Converted printing code over ot using DumpTriple() rather than
building from scratch.
* Fixed up a couple places that were not guaranteeing that an
unspecified unknown was recorded as such.

Summary:
`IsRelativeToCurrentWorkingDirectory` was misleading, because relative paths
are sometimes appended to other directories, not just the cwd. Plus, the new
name is shorter. Also added `IsAbsolute` for completeness.

Summary:
Fixes http://reviews.llvm.org/D8511
The original method of using dladdr() could return the incorrect relative
path if not dynamically linked against liblldb and the working directory
has changed. This is not a problem when built with python, since
ScriptInterpreterPython::InitializePrivate calls
HostInfo::GetLLDBPath(ePathTypeLLDBShlibDir, ...) and caches the
correct path before any changes to the working directory.
The /proc/self/exe approach fails if run using Python, but works for all other
cases (including for android, which doesn't have dladdr()).
So if we combine the two, we should reasonably cover all corner cases.

Summary:
ComputeSupportExeDirectory relied on ComputeSharedLibraryDirectory which was
not always reliable. Using procfs seems to be the best way to deal with it on
Linux (since it's already done on Android, might as well merge it).

This was causing code that opened multiple targets to try and get a path to debugserver from the GDB remote communication class, and it would get the LLDB path and some instances would return empty strings and it would cause debugserver to not be found.

This patch moves creates a thread abstraction that represents a
thread running inside the LLDB process. This is a replacement for
otherwise using lldb::thread_t, and provides a platform agnostic
interface to managing these threads.

This should bring HostInfo up to 99% completion. The remainder

This continues the effort to get Host code moved over to HostInfo,
and removes many more instances of preprocessor defines along the
way.

This patch creates a HostInfo class, a static class used to answer
basic queries about the host platform. As part of this change,
some functionality is moved from Host to HostInfo, and relevant
fixups are performed in the rest of the codebase.
This is part of a larger effort to isolate more code in the Host
layer into platform-specific groups, to make it easier to make
platform specific changes for a particular Host without breaking
other hosts.
