db1e9981b8 Remove memory corruption bug. string.c_str() was returning a temporary that was
dead before we used it.

d42b58b61c Fix libLTO:
* Call InitializeAllTargets on every path where we might query the
   TargetRegistry. This fixes PR4604.
 * flush the formatted_raw_ostream& or else not all of the assembly will make
   it to the .s file. (It doesn't do this in its destructor?!)
 * Due to a reversed conditional, libLTO was reporting many symbols as both
   defined and undefined, including two definitions of the same symbol name
   in its symbol list.

a5881e3060 Add TargetRegistry::lookupTarget.
- This is a simplified mechanism which just looks up a target based on the
   target triple, with a few additional flags.

 - Remove getClosestStaticTargetForModule, the moral equivalent is now:
     lookupTarget(Mod->getTargetTriple, true, false, ...);

 - This no longer does the fuzzy matching with target data (based on endianness
   and pointer width) that getClosestStaticTargetForModule was doing, but this
   was deemed unnecessary.

6316fbcb04 Convert StringMap to using StringRef for its APIs.
- Yay for '-'s and simplifications!

 - I kept StringMap::GetOrCreateValue for compatibility purposes, this can
   eventually go away. Likewise the StringMapEntry Create functions still follow
   the old style.

 - NIFC.

b8158acc23 Reapply my previous asmprinter changes now with more testing and two
additional bug fixes:

1. The bug that everyone hit was a problem in the asmprinter where it
   would remove $stub but keep the L prefix on a name when emitting the
   indirect symbol.  This is easy to fix by keeping the name of the stub
   and the name of the symbol in a StringMap instead of just keeping a
   StringSet and trying to reconstruct it late.

2. There was a problem printing the personality function.  The current
   logic to print out the personality function from the DWARF information
   is a bit of a cesspool right now that duplicates a bunch of other 
   logic in the asm printer.  The short version of it is that it depends
   on emitting both the L and _ prefix for symbols (at least on darwin)
   and until I can untangle it, it is best to switch the mangler back to
   emitting both prefixes.

0a5372ed3e Begin the painful process of tearing apart the rat'ss nest that is Constants.cpp and ConstantFold.cpp.
This involves temporarily hard wiring some parts to use the global context.  This isn't ideal, but it's
the only way I could figure out to make this process vaguely incremental.

e0f0e0be1c Change LTO to run the global opt pass twice.
- This matches llvm-ld.

It took a bit of archeology to figure out what the right thing to do was
(whether this was intentionally added or intentionally removed). My final
conclusion is that Chris added this intentionally here:
  http://llvm.org/viewvc/llvm-project?view=rev&revision=16913
but the changes weren't propogated to llvm-ld until here:
  http://llvm.org/viewvc/llvm-project?view=rev&revision=34058
which was after lto.cpp had been cloned off (of llvm-ld), here:
  http://llvm.org/viewvc/llvm-project?view=rev&revision=29494

From the commit message, it looks like the motivation for running global opt
again is because we ran it prior to inlining. Based on that I updated the
comment and also only run the pass if we actually ran the inliner.

Chris, please review.
