Fix aranges and split dwarf by ensuring that the symbol and relocation
back to the compile unit from the aranges section is to the skeleton
unit and not the one in the dwo.

Do this by adding a method to grab a forwarded on local sym and local
section by querying the skeleton if one exists and using that. Add
a few tests to verify the relocations are back to the correct section.

[CMake][VS][XCode] Restruct the output directory layout more comfortable, ${BINARY_DIR}/${BUILD_MODE}/(bin|lib)

We have been seeing nasty directory layout with CMake multiconfig, such as,
  bin/Release/clang.exe
  lib/clang/3.x/...
  lib/Release/clang/3.x/.. (duplicated)

Move the layout similar to autoconf's;
  Release/bin/clang.exe
  Release/lib/clang/3.x/...

Checked on Visual Studio 10. Could you guys please confirm my change on XCode(and other multiconfig builders)?

Note: Don't set variables CMAKE_*_OUTPUT_DIRECTORY any more, or a certain builder, for eaxample, msbuild.exe, would be confused.

Revert r198199 (and r198202). It broke 3 DebugInfo tests for targeting i686-cygming.

  r198196: Use a pointer to keep track of the skeleton unit for each normal unit and construct it up front.
  r198199: Reapply r198196 with a fix to zero initialize the skeleton pointer.
  r198202: Fix aranges and split dwarf by ensuring that the symbol and relocation back to the compile unit from the aranges section is to the skeleton unit and not the one in the dwo.

They could be reproducible with explicit target.

Revert r198208 and reapply:

      r198196: Use a pointer to keep track of the skeleton unit for each normal unit and construct it up front.
      r198199: Reapply r198196 with a fix to zero initialize the skeleton pointer.
      r198202: Fix aranges and split dwarf by ensuring that the symbol and relocation back to the compile unit from the aranges section is to the skeleton unit and not the one in the dwo.

with a fix to use integer 0 for DW_AT_low_pc since the relocation to the text section symbol was causing issues with COFF. Accordingly remove addLocalLabelAddress and machinery since we're not currently using it.

ARM IAS: account for predicated pre-UAL mnemonics

Checking the trailing letter of the mnemonic is insufficient.  Be more thorough
in the scanning of the instruction to ensure that we correctly work with the
predicated mnemonics.
