ba2a226fab Try harder to get a consistent floating point results.
This just extends the existing hack. It should be enough to get a reproducible bootstrap
on 32 bits.

I will open a bug to track getting a real fix for this.

193140b085 DebugInfo: Remove unused start/end labels for the debug_abbrevs section
Since we always emit only one abbrevation section (shared by all the
compilation units in this module) there's no need for a separate label
at the start of each one (and we weren't using the CU ID anyway, so
there really was only one label). Use the section label instead and drop
the wholely unused debug_abbrev_end label.

eae8ef479d Added MachineBlockFrequencyInfo::view for displaying the block frequency propagation graph via graphviz.

since one can easily visualize where probability mass and other errors
occur in the propagation.

1cbca515b6 Refactor a lot of patchpoint/stackmap related code to simplify and make it
target independent.

Most of the x86 specific stackmap/patchpoint handling was necessitated by the
use of the native address-mode format for frame index operands. PEI has now
been modified to treat stackmap/patchpoint similarly to DEBUG_INFO, allowing
us to use a simple, platform independent register/offset pair for frame
indexes on stackmap/patchpoints.

Notes:
  - Folding is now platform independent and automatically supported.
  - Emiting patchpoints with direct memory references now just involves calling
    the TargetLoweringBase::emitPatchPoint utility method from the target's
    XXXTargetLowering::EmitInstrWithCustomInserter method. (See
    X86TargetLowering for an example).
  - No more ugly platform-specific operand parsers.

This patch shouldn't change the generated output for X86.

823c9c725d Use simple section names for COMDAT sections on COFF.
With this patch we use simple names for COMDAT sections (like .text or .bss).
This matches the MSVC behavior.

When merging it is the COMDAT symbol that is used to decide if two sections
should be merged, so there is no point in building a fancy name.

This survived a bootstrap on mingw32.
