e04360918b SelectionDAG: Use helper function to improve legalization of ISD::MUL

fdde7d2110 SelectionDAG: Factor ISD::MUL lowering code out of DAGTypeLegalizer
This code has been moved to a new function in the TargetLowering
class called expandMUL().  The purpose of this is to be able
to share lowering code between the SelectionDAGLegalize and
DAGTypeLegalizer classes.

No functionality changed intended.

eb0c9094ac [yaml2obj][ELF] ELF Relocations Support.
The patch implements support for both relocation record formats: Elf_Rel
and Elf_Rela. It is possible to define relocation against symbol only.
Relocations against sections will be implemented later. Now yaml2obj
recognizes X86_64, MIPS and Hexagon relocation types.

Example of relocation section specification:
Sections:
- Name: .text
  Type: SHT_PROGBITS
  Content: "0000000000000000"
  AddressAlign: 16
  Flags: [SHF_ALLOC]

- Name: .rel.text
  Type: SHT_REL
  Info: .text
  AddressAlign: 4
  Relocations:
    - Offset: 0x1
      Symbol: glob1
      Type: R_MIPS_32
    - Offset: 0x2
      Symbol: glob2
      Type: R_MIPS_CALL16

The patch reviewed by Michael Spencer, Sean Silva, Shankar Easwaran.

77cf856e56 Implement depth_first and inverse_depth_first range factory functions.
Also updated as many loops as I could find using df_begin/idf_begin -
strangely I found no uses of idf_begin. Is that just used out of tree?

Also a few places couldn't use df_begin because either they used the
member functions of the depth first iterators or had specific ordering
constraints (I added a comment in the latter case).

Based on a patch by Jim Grosbach. (Jim - you just had iterator_range<T>
where you needed iterator_range<idf_iterator<T>>)

fe25521451 Reimplement debug info compression by compressing the whole section, rather than a fragment.
To support compressing the debug_line section that contains multiple
fragments (due, I believe, to variation in choices of line table
encoding depending on the size of instruction ranges in the actual
program code) we needed to support compressing multiple MCFragments in a
single pass.

This patch implements that behavior by mutating the post-relaxed and
relocated section to be the compressed form of its former self,
including renaming the section.

This is a more flexible (and less invasive, to a degree) implementation
that will allow for other features such as "use compression only if it's
smaller than the uncompressed data".

Compressing debug_frame would be a possible further extension to this
work, but I've left it for now. The hurdle there is alignment sections -
which might require going as far as to refactor
MCAssembler.cpp:writeFragment to handle writing to a byte buffer or an
MCObjectWriter (there's already a virtual call there, so it shouldn't
add substantial compile-time cost) which could in turn involve
refactoring MCAsmBackend::writeNopData to use that same abstraction...
which involves touching all the backends. This would remove the limited
handling of fragment writing seen in
ELFObjectWriter.cpp:getUncompressedData which would be nice - but it's
more invasive.

I did discover that I (perhaps obviously) don't need to handle
relocations when I rewrite the fragments - since the relocations have
already been applied and computed (and stored into
ELFObjectWriter::Relocations) by this stage (necessarily, because we
need to have written any immediate values or assembly-time relocations
into the data already before we compress it, which we have). The test
case doesn't necessarily cover that in detail - I can add more test
coverage if that's preferred.

e7ef041ba4 For the ARM integrated assembler add checking of the
alignments on vld/vst instructions.  And report errors for
alignments that are not supported.

While this is a large diff and an big test case, the changes
are very straight forward.  But pretty much had to touch
all vld/vst instructions changing the addrmode to one of the
new ones that where added will do the proper checking for
the specific instruction.

FYI, re-committing this with a tweak so MemoryOp's default
constructor is trivial and will work with MSVC 2012. Thanks
to Reid Kleckner and Jim Grosbach for help with the tweak.

afb4ef3549 Add support for load folding of avx1 logical instructions
AVX supports logical operations using an operand from memory. Unfortunately
because integer operations were not added until AVX2 the AVX1 logical
operation's types were preventing the isel from folding the loads. In a limited
number of cases the peephole optimizer would fold the loads, but most were
missed. This patch adds explicit patterns with appropriate casts in order for
these loads to be folded.

The included test cases run on reduced examples and disable the peephole
optimizer to ensure the folds are being pattern matched.
