f69a29b23a Revert "Fix the build broken by r189315." and "Move everything depending on Object/MachOFormat.h over to Support/MachO.h."
This reverts commits r189319 and r189315. r189315 broke some tests on what I
believe are big-endian platforms.

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.

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.

da25cd3e6d SelectionDAG: Use correct pointer size when lowering function arguments v2
This adds minimal support to the SelectionDAG for handling address spaces
with different pointer sizes.  The SelectionDAG should now correctly
lower pointer function arguments to the correct size as well as generate
the correct code when lowering getelementptr.

This patch also updates the R600 DataLayout to use 32-bit pointers for
the local address space.

v2:
  - Add more helper functions to TargetLoweringBase
  - Use CHECK-LABEL for tests

ea57433cee Adds cyclic critical path computation and heuristics, temporarily disabled.
Estimate the cyclic critical path within a single block loop. If the
acyclic critical path is longer, then the loop will exhaust OOO
resources after some number of iterations. If lag between the acyclic
critical path and cyclic critical path is longer the the time it takes
to issue those loop iterations, then aggressively schedule for
latency.

a8a7099c18 Turn MipsOptimizeMathLibCalls into a target-independent scalar transform
...so that it can be used for z too.  Most of the code is the same.
The only real change is to use TargetTransformInfo to test when a sqrt
instruction is available.

The pass is opt-in because at the moment it only handles sqrt.

registers through other means, like SPARC's register windows.

f73826bef0 Add a new helper method to Value to strip in-bounds constant offsets of
pointers, but accumulate the offset into an APInt in the process of
stripping it.

This is a pretty handy thing to have, such as when trying to determine
if two pointers are at some constant relative offset. I'll be committing
a patch shortly to use it for exactly that purpose.

f7ab3a84b3 ARM: use TableGen patterns to select CMOV operations.
Back in the mists of time (2008), it seems TableGen couldn't handle the
patterns necessary to match ARM's CMOV node that we convert select operations
to, so we wrote a lot of fairly hairy C++ to do it for us.

TableGen can deal with it now: there were a few minor differences to CodeGen
(see tests), but nothing obviously worse that I could see, so we should
probably address anything that *does* come up in a localised manner.

171ac8ca17 MC CFG: Add YAML MCModule representation to enable MC CFG testing.
Like yaml ObjectFiles, this will be very useful for testing the MC CFG
implementation (mostly MCObjectDisassembler), by matching the output
with YAML, and for potential users of the MC CFG, by using it as an input.

There isn't much to the actual format, it is just a serialization of the
MCModule class. Of note:
  - Basic block references (pred/succ, ..) are represented by the BB's
    start address.
  - Just as in the MC CFG, instructions are MCInsts with a size.
  - Operands have a prefix representing the type (only register and
    immediate supported here).
  - Instruction opcodes are represented by their names; enum values aren't
    stable, enum names mostly are: usually, a change to a name would need
    lots of changes in the backend anyway.
    Same with registers.

All in all, an example is better than 1000 words, here goes:

A simple binary:

  Disassembly of section __TEXT,__text:
  _main:
  100000f9c:      48 8b 46 08             movq    8(%rsi), %rax
  100000fa0:      0f be 00                movsbl  (%rax), %eax
  100000fa3:      3b 04 25 48 00 00 00    cmpl    72, %eax
  100000faa:      0f 8c 07 00 00 00       jl      7 <.Lend>
  100000fb0:      2b 04 25 48 00 00 00    subl    72, %eax
  .Lend:
  100000fb7:      c3                      ret

And the (pretty verbose) generated YAML:

d7d43dc435 DebugInfo: Do not use the DWARF Version for the .debug_pubnames or .debug_pubtypes version field
Summary:
LLVM would generate DWARF with version 3 in the .debug_pubname and
.debug_pubtypes version fields.  This would lead SGI dwarfdump to fail
parsing the DWARF with (in the instance of .debug_pubnames) would exit
with:
dwarfdump ERROR:  dwarf_get_globals: DW_DLE_PUBNAMES_VERSION_ERROR (123)

This fixes PR16950.

8c20158fb0 [SystemZ] Use SRST to optimize memchr
SystemZTargetLowering::emitStringWrapper() previously loaded the character
into R0 before the loop and made R0 live on entry.  I'd forgotten that
allocatable registers weren't allowed to be live across blocks at this stage,
and it confused LiveVariables enough to cause a miscompilation of f3 in
memchr-02.ll.

This patch instead loads R0 in the loop and leaves LICM to hoist it
after RA.  This is actually what I'd tried originally, but I went for
the manual optimisation after noticing that R0 often wasn't being hoisted.
This bug forced me to go back and look at why, now fixed as r188774.

We should also try to optimize null checks so that they test the CC result
of the SRST directly.  The select between null and the SRST GPR result could
then usually be deleted as dead.
