class.  Change Resolver to no longer use Platform.  Core linking
now issues errors directly.  We need to factor that out later.

Rework how Darwin executable writer finds "main" atom.  It now
adds to core linking an Atom  which has a Reference to "main".

r155047. See the LLVM log for the primary motivation:
  http://llvm.org/viewvc/llvm-project?rev=155047&view=rev

Primary commit r154828:
  - Several issues were raised in review, and fixed in subsequent
    commits.
  - Follow-up commits also reverted, and which should be folded into the
    original before reposting:
    - r154837: Re-add the 'undef BUILTIN' thing to fix the build.
    - r154928: Fix build warnings, re-add (and correct) header and
      license
    - r154937: Typo fix.

Please resubmit this patch with the relevant LLVM resubmission.

commits have had several major issues pointed out in review, and those
issues are not being addressed in a timely fashion. Furthermore, this
was all committed leading up to the v3.1 branch, and we don't need piles
of code with outstanding issues in the branch.

It is possible that not all of these commits were necessary to revert to
get us back to a green state, but I'm going to let the Hexagon
maintainer sort that out. They can recommit, in order, after addressing
the feedback.

Reverted commits, with some notes:

Primary commit r154616: HexagonPacketizer
  - There are lots of review comments here. This is the primary reason
    for reverting. In particular, it introduced large amount of warnings
    due to a bad construct in tablegen.
  - Follow-up commits that should be folded back into this when
    reposting:
    - r154622: CMake fixes
    - r154660: Fix numerous build warnings in release builds.
  - Please don't resubmit this until the three commits above are
    included, and the issues in review addressed.

Primary commit r154695: Pass to replace transfer/copy ...
  - Reverted to minimize merge conflicts. I'm not aware of specific
    issues with this patch.

Primary commit r154703: New Value Jump.
  - Primarily reverted due to merge conflicts.
  - Follow-up commits that should be folded back into this when
    reposting:
    - r154703: Remove iostream usage
    - r154758: Fix CMake builds
    - r154759: Fix build warnings in release builds
  - Please incorporate these fixes and and review feedback before
    resubmitting.

Primary commit r154829: Hexagon V5 (floating point) support.
  - Primarily reverted due to merge conflicts.
  - Follow-up commits that should be folded back into this when
    reposting:
    - r154841: Remove unused variable (fixing build warnings)

There are also accompanying Clang commits that will be reverted for
consistency.

Make sure EmulateInstructionARM doesn't have to have "armv4", "armv6", "armv7" as the exact architecture name, the arch name can just start with any of these strings. We need to be able to recognize different variants that might come along and not fail to backtrace completely (which happens when we aren't able to find an architecture that matches) when we don't have exact matches.

Richard Smith:  __int128 is a GNU keyword which clang 3.1 supports. This usage of it as an identifier will need to be renamed.

LiveIntervalUpdate validators weren't recorded after the calls to std::for_each.  Turns out std::for_each doesn't update the variable passed in for the functor but instead copy constructs a new one.

StringMap iterators are not deterministic, and that's more important
here than speed or memory.

Fix the bahavior of the disassembler when decoding unpredictable mrs instructions on ARM. Now the diasassembler emmits warnings instead of errors.

llvm-svn: 155002

Added support for unpredictable mcrr/mcrr2/mrrc/mrrc2 ARM instruction in the disassembler. Since the upredicability conditions are complex, C++ code was added to handle them.

llvm-svn: 155001

Fixed decoding for the ARM cdp2 instruction. The restriction on the coprocessor number was removed for this instruction.

llvm-svn: 155000

Add suport for unpredicatble cases of the cmp, tst, teq and cmnz ARM instructions in the disassembler.

DenseMap's hash function uses slightly more entropy and reduces hash collisions
significantly.  I also experimented with Hashing.h, but it didn't gave a lot of
improvement while being much more expensive to compute.

backend flags in TargetOptions.h into their own class in r145714.
