- Used xfail and skip, temporarily, while resolving bugzilla #15671.

Allow LLDB to be built on a system with an installed gcc/g++ that isn't the default. I recently installed gcc-4.7/g++-4.7 on Ubuntu and tried to build by specifying:

CC=gcc-4.7 CXX=g++-4.7

as configure and make args, but it didn't work when being run with makefiles. This patch fixes that.

- copy lldb python module into directory specified with CMAKE_INSTALL_PREFIX
- make liblldb.so a symlink (to liblldb.so.X.Y where X.Y is the LLVM version)

- Note that this is not correct, as the failure is associated with build options of libc.so, however it's failing on a Debian buildbot that uses gcc 4.6.2 (and the real goal is a complete backtrace even with -fomit-frame-pointer).

- Adds helpers to lldbtest.py to check the expectedCompiler and expectedVersion, with an eventual goal of reducing the number of test decorators.
--- Currently allows a comparison operator and a compiler version to be specified.
--- Can be extended to support ranges of compiler versions.

-Remove tracing of fork/vfork until we add support for tracing inferiors' children on Linux.
-Add trace exec option for ptrace so that we don't receive legacy SIGTRAP signals on execve calls.
-Add handling of SIGCHLD sent by kernel (for now, deliver the signal to the inferior).

- now, the output binary is called 'lldb-3.4' instead of 'lldb'
- a symlink 'lldb' -> 'lldb-3.4' is also created
- this fixes one of the problems preventing CMake from building Debian packages

Before, we had an unused internal_getpid function for Linux, and a
platform-independent GetPid function.  To make the naming conventions
consistent for syscall-like functions, the GetPid syscall wrapper
in sanitizer_posix.cc is moved to sanitizer_mac.cc, and GetPid is
renamed to internal_getpid, bringing the Linux variant into use.

Dot4 now uses 8 scalar operands instead of 2 vectors one which allows register
coalescer to remove some unneeded COPY.
This patch also defines some structures/functions that can be used to handle
every vector instructions (CUBE, Cayman special instructions...) in a similar
fashion.

Almost all instructions that takes a 128 bits reg as input (fetch, export...)
have the abilities to swizzle their argument and output. Instead of printing
default swizzle for each 128 bits reg, rename T*.XYZW to T* and let instructions
print potentially optimized swizzles themselves.

Introduce a new object library, RTSanitizerCommonLibc, which will contain
the subset of sanitizer_common with libc dependencies. RTSanitizerCommon
contains the remainder of sanitizer_common, and is intended to have no
libc dependencies. Begin moving code to RTSanitizerCommonLibc, starting
with sanitizer_common.cc, whose libc-dependent portion is moved to
sanitizer_common_libcdep.cc, the first member of the new library.

This split affects the CMake build only.  The makefile build continues
to produce the full sanitizer_common library.

- On Linux, the partial back-trace after an assert can cause the basic test to fail as discussed on lldb-dev.
- Uses SBFrame to walk up the stack to the assert site and tests expression evaluation of locals, globals and arguments.

Thanks to Daniel for review and testing on OS/X.

UseAuto used to match initialized variable declarations independently of
whether they were defined in a declaration list or as a single declaration.
Now it matches declaration statements where every variable declaration is
initialized.

Shuffles that only move an element into position 0 of the vector are common in
the output of the loop vectorizer and often generate suboptimal code when SSSE3
is not available. Lower them to vector shifts if possible.

We still prefer palignr over psrldq because it has higher throughput on
sandybridge.
