am 1c4ad5ef: Merge branch \'upstream\' into merge-2012_09_10

* commit '1c4ad5ef4fab105f0c8af7edd026e00502fb6279': (446 commits)
  Revert r163556. Missed updates to tablegen files.
  Update function names to conform to guidelines.  No functional change intended.
  test/CodeGen/X86/ms-inline-asm.ll: Relax for non-darwin x86 targets. '##InlineAsm' could not be seen in other hosts.
  [ms-inline asm] Properly emit the asm directives when the AsmPrinterVariant and InlineAsmVariant don't match.
  Update test case for Release builds.
  Remove redundant semicolons which are null statements.
  Disable stack coloring because it makes dragonegg fail bootstrapping.
  [ms-inline asm] Pass the correct AsmVariant to the PrintAsmOperand() function and update the printOperand() function accordingly.
  [ms-inline asm] Add support for .att_syntax directive.
  Enable stack coloring.
  Don't attempt to use flags from predicated instructions.
  [Object] Extract Elf_Ehdr. Patch by Hemant Kulkarni!
  Stack Coloring: Handle the case where END markers come before BEGIN markers properly.
  Enhance PR11334 fix to support extload from v2f32/v4f32
  Add "blocked" heuristic to the Hexagon MI scheduler.
  Fold multiply by 0 or 1 when in UnsafeFPMath mode in SelectionDAG::getNode().
  whitespace
  Add boolean simplification support from CMOV
  Fix an assertion failure when optimising a shufflevector incorrectly into concat_vectors, and a followup bug with SelectionDAG::getNode() creating nodes with invalid types.
  Minor cleanup. No functional change.
