Todd Fiala 58a2f6692b llgs: corrected Linux signal reception notification for SIGABRT, SIGSEGV and their ilk.
Added llgs/debugserver gdb-remote tests around SIGABRT and SIGSEGV signal reception
notification.  Found a few bugs in exception signal handling in Linux llgs.  Fixed those.

Todd Fiala 202ecd26da Fixes for broken Debian build - g++ 4.7 support.
These fix the broken debian lldb build, which is using g++ 4.7.2.

TypeFormat changes:
1. stopped using the C++11 "dtor = default;" construct.
The generated default destructor in the two derived classes wanted
them to have a different throws() semantic that was causing 4.7 to
fail to generate it.  I switched these to empty destructors defined
in the .cpp file.

2. Switched the m_types map from an ordered map to an unordered_map.
g++ 4.7's c++ library supports the C++11 emplace() used by TypeFormat
but the same c++ library's map impl does not.  Since TypeFormat didn't
look like it depended on ordering in the map, I just switched it to
a std::unordered_map.

NativeProcessLinux - g++ 4.7 chokes on lexing the "<::" in
static_cast<::pid_t>(wpid).  g++ 4.8+ and clang are fine with it.
I just put a space in between the "<" and the "::" and that cleared
it up.

Todd Fiala dda6194399 lldb - problem with some PTRACE_* constants in NativeProcessLinux.cpp file
See http://reviews.llvm.org/D4366 for details.

Change by Paul Paul Osmialowski

Today this is the only problem that I'm facing trying to cross-compile lldb for AArch64 using Linaro's toolchain.

PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS, PTRACE_SETFPREGS are not defined for AArch64
These things can be defined different ways for other architectures, e.g. for x86_64 Linux, asm/ptrace-abi.h defines them as preprocessor constants while sys/ptrace.h defines them in enum along with corresponding PT_* preprocessor constants
NativeProcessLinux.cpp includes sys/ptrace.h
To avoid accidental redefinition of enums with preprocessor constants, I'm proposing this patch which first checks for PT_* preprocessor constants then checks for PTRACE_* constants then when it still can not find them, it defines preprocessor constants.
Similar approach was already used for PTRACE_GETREGSET and PTRACE_SETREGSET constants; in this case however it was easier, since enum values in sys/ptrace.h and preprocessor constants shared all exactly the same names (e.g. there's no additional PT_GETREGSET name defined).

Todd Fiala af245d115b Add lldb-gdbserver support for Linux x86_64.
This change brings in lldb-gdbserver (llgs) specifically for Linux x86_64.
(More architectures coming soon).

Not every debugserver option is covered yet.  Currently
the lldb-gdbserver command line can start unattached,
start attached to a pid (process-name attach not supported yet),
or accept lldb attaching and launching a process or connecting
by process id.

The history of this large change can be found here:
https://github.com/tfiala/lldb/tree/dev-tfiala-native-protocol-linux-x86_64

Until mid/late April, I was not sharing the work and continued
to rebase it off of head (developed via id tfiala@google.com).  I switched over to
user todd.fiala@gmail.com in the middle, and once I went to github, I did
merges rather than rebasing so I could share with others.
