842a1be06c [SystemZ] Extend memcpy and memset support to all constant lengths
Lengths up to a certain threshold (currently 6 * 256) use a series of MVCs.
Lengths above that threshold use a loop to handle X*256 bytes followed
by a single MVC to handle the excess (if any).  This loop will also be
needed in future when support for variable lengths is added.

Because the same tablegen classes are used to define MVC and CLC,
the patch also has the side-effect of defining a pseudo loop instruction
for CLC.  That instruction isn't used yet (and wouldn't be handled correctly
if it were).  I'm planning to use it soon though.

63fd2af389 Add support for DebugFission to DWARF parser
Summary:
1) Make llvm-symbolizer properly symbolize
files with split debug info (by using stanalone .dwo files).
2) Make DWARFCompileUnit parse and store corresponding .dwo file,
if necessary.
3) Make bits of DWARF parsing more CompileUnit-oriented.

bf778d0546 Support/MachO: Add a bunch of defines.
Right now we have two headers for the Mach-O format. I'd like to get rid
of one. Since the other object formats are all in Support, I chose to
keep the Mach-O header in Support, and discard the other one.

f0a0d57808 Fix wrong code offset for unwind code SET_FPREG.
The code offset for unwind code SET_FPREG is wrong because it is set
to constant 0. The fix is to do the same as for the other unwind
codes: emit a label and later the absolute difference between the
label and the begin of the prologue.
Also enables the failing test case MC/COFF/seh.s

e3427a5815 Add new API lto_codegen_compile_parallel().
This API is proposed by Nick Kledzik. The semantic is:

  --------------------------------------------------------------------------
   Generate code for merged module into an array of native object files. On 
   success returns a pointer to an array of NativeObjectFile.  The count 
   parameter returns the number of elements in the array.  Each element is 
   a pointer/length for a generated mach-o/ELF buffer.  The buffer is owned
   by the lto_code_gen_t and will be freed when lto_codegen_dispose() is called, 
   or lto_codegen_compile() is called again. On failure, returns NULL 
   (check lto_get_error_message() for details).

   extern const struct  NativeObjectFile*
   lto_codegen_compile_parallel(lto_code_gen_t cg, size_t *count);
  ---------------------------------------------------------------------------

  This API is currently only called on OSX platform. Linux or other Unixes
using GNU gold are not supposed to call this function, because on these systems, 
object files are fed back to linker via disk file instead of memory buffer.

  In this commit, lto_codegen_compile_parallel() simply calls
lto_codegen_compile() to return a single object file. In the near future,
this function is the entry point for compilation with partition. Linker can
blindly call this function even if partition is turned off; in this case,
compiler will return only one object file.

6e3cd0ebe2 Debug Info: add an identifier field to DICompositeType.
DICompositeType will have an identifier field at position 14. For now, the
field is set to null in DIBuilder.
For DICompositeTypes where the template argument field (the 13th field)
was optional, modify DIBuilder to make sure the template argument field is set.
Now DICompositeType has 15 fields.

Update DIBuilder to use NULL instead of "i32 0" for null value of a MDNode.
Update verifier to check that DICompositeType has 15 fields and the last
field is null or a MDString.

Update testing cases to include an extra field for DICompositeType.
The identifier field will be used by type uniquing so a front end can
genearte a DICompositeType with a unique identifer.

bb4066123d ARM: Fix ELF global base reg intialization.
The create machine code wasn't properly in SSA, which the machine verifier
properly complains about. Now that fast-isel is closer to verifier clean,
errors like this show up more clearly.

Additionally, the Thumb pseudo tPICADD was used for both ARM and Thumb
mode functions, which is obviously wrong. Fix that along the way.

Test case is part of the following commit which will finish making an
additional fast-isel test verifier clean an enable it for the
regression test suite. This commit is separate since its not just
a verifier cleanup, but an actual correctness issue.

055d207426 [PowerPC] More fast-isel chunks (returns and integer extends)
Incremental improvement to fast-isel for PPC64.  This allows us to
select on ret, sext, and zext.  Filling in sext/zext improves some of
the existing logic in handling compare-immediates that needed extends.

A simplified return convention for fast-isel is also added to the
PPC64 calling conventions.  All call/return processing for DAG
selection is handled with custom code, so there isn't an existing CC
to rely on here.  The include of PPCGenCallingConv.inc causes compiler
warnings due to the 32-bit calling conventions that are not used, so
the dummy function "usePPC32CCs()" is added here to silence those.

Test cases for the return and extend logic are added.

always available in bin/ (regardless of the configuration LLVM is
built with).
