7bf3d6a043 Previously, parsing capability of the .debug_frame section was added
to lib/DebugInfo, with dumping in llvm-dwarfdump. This patch adds
initial ability to parse and dump CFA instructions contained in
entries.

To keep it manageable, the patch omits some more advanced capabilities
(accounted in TODOs):

* Parsing of instructions with BLOCK arguments (expression lists)
* Dumping of actual instruction arguments (currently only names are
dumped). This is quite tricky since the dumper has to effectively
"interpret" the instructions.

c23197a26f llvm_unreachable->llvm_unreachable(0), LLVM_UNREACHABLE->llvm_unreachable.
This adds location info for all llvm_unreachable calls (which is a macro now) in
!NDEBUG builds.
In NDEBUG builds location info and the message is off (it only prints
"UREACHABLE executed").

c25e7581b9 assert(0) -> LLVM_UNREACHABLE.
Make llvm_unreachable take an optional string, thus moving the cerr<< out of
line.
LLVM_UNREACHABLE is now a simple wrapper that makes the message go away for
NDEBUG builds.

13319ceffd The debugger sometimes lookup dynamically in the runtime to find ivar info of any Objective-C classes. It would be very helpful to debugger if the compiler encodes runtime version number in DWARF.
Add support for two additional DWARF attributes to encode Objective-C runtime version number.

3b64c6bc29 Introduce two DWARF attribute extentions DW_AT_APPLE_optimized, DW_AT_APPLE_flags.
DW_AT_APPLE_optimized flag is set when a compile_unit is optimized. The debugger takes advantage of this information some way.

DW_AT_APPLE_flags encodes command line options when certain env. variable is set. This is used by build engineers to track various gcc command lines used by by  a project, irrespective of whether the project used makefile, Xcode or something else.

llvm-gcc patch is next.

7107c3badf For PR780:
1. Move IncludeFile.h to System library
2. Move IncludeFile.cpp to System library
3. #1 and #2 required to prevent cyclic library dependencies for libSystem
4. Convert all existing uses of Support/IncludeFile.h to System/IncludeFile.h
5. Add IncludeFile support to various lib/System classes.
6. Add new lib/System classes to LinkAllVMCore.h
All this in an attempt to pull in lib/System to what's required for VMCore
