All the other paths in the find_toolchain function return a tuple
(detected_toolchain_type, compiler_path), but when the parameter to
--compiler is not one of the predefined names it only returns the
detected toolchain type, which causes an error when trying to unpack the
result.
This patch changes it to return also the compiler path passed as a
parameter.

Pass appropriate -L and -Wl,-rpath flags pointing out to the LLVM
library directory on NetBSD. This is necessary since clang on NetBSD
requires libc++ but it is not installed as part of the system
by default. For the purpose of running buildbot, we want LLDB to use
just-built libc++.

Summary:
clang-cl tries to match cl's interface, and treats /U as "Removes a
predefined macro" as cl does. When you feed clang-cl a file that begins with
'/U' (e.g. /Users/xiaobai/foo.c), clang-cl will emit a warning and in some cases
an error, like so:
clang-9: warning: '/Users/xiaobai/foo.c' treated as the '/U' option [-Wslash-u-filename]
clang-9: note: Use '--' to treat subsequent arguments as filenames
clang-9: error: no input files
If you're using clang-cl, make sure '--' is passed before the source file.

Summary:
`clang-cl` can't compile tests containing `char16_t` and `char32_t` types
without the MSVC compatibility option passed. This patch adds the option to the
`clang-cl` call in the `build.py` script by default.

Fix the build helper to find lld-link via PATH lookup, rather than
making a fragile assumption that it will be present in the 'compiler
directory'. This fixes tests on Gentoo where clang and lld
are installed in different directories.

Summary:
This should enable the compiler to find the system linker for the link
step.

Summary:
This implements the gcc builder in build.py script to allow it to
compile host executables when running on a non-windows host. Where it
made sense, I tried to share code with the msvc builder by moving stuff
to the base class.

In compile-and-link mode, the user doesn't specify the name of the
object files to generate, because there could be multiple inputs
on a single command line and this would be hard to specify. So the
script just tries to be smart and figure out the best object file
names. However, if two build scripts are running in parallel and
using the same source files as input, they would previously race
to write the same object files, since the computed name only considered
the source file names when computing the object file names.
With this patch, we also consider the final executable name. In a
way, this "namespaces" the generated object files so that as long
as the final executable file names don't clash, the intermediate
object file names won't clash either.

This makes -mode=compile support multiple inputs (and hence
multiple outputs).
It also makes the value of -arch for compiling inferiors default
to the architecture that LLDB is built in. This can still be
overridden however.

This adds a script called build.py as well as a lit substitution
called %build that we can use to invoke it. The idea is that
this allows a lit test to build test inferiors without having
to worry about architecture / platform specific differences,
command line syntax, finding / configurationg a proper toolchain,
and other issues. They can simply write something like:
%build --arch=32 -o %t.exe %p/Inputs/foo.cpp
and it will just work. This paves the way for being able to
run lit tests with multiple configurations, platforms, and
compilers with a single test.
