two address instructions.  We need to keep track of things we've processed AS USES
independetly of whether we've processed them as defs.

This fixes all known miscompilations when reconstruction is turned on.

- Simplify ParseDeclCXX to use early exit on error instead of nesting.
- Change ParseDeclCXX to using the 'skip on error' form of ExpectAndConsume.
- If we don't see the ; in a using directive, still call the action, for 
  hopefully better error recovery.

information for declarations that were referenced via a qualified-id,
e.g., N::C::value. We keep track of the location of the start of the
nested-name-specifier. Note that the difference between
QualifiedDeclRefExpr and DeclRefExpr does have an effect on the
semantics of function calls in two ways:
  1) The use of a qualified-id instead of an unqualified-id suppresses
     argument-dependent lookup
  2) If the name refers to a virtual function, the qualified-id
  version will call the function determined statically while the
  unqualified-id version will call the function determined dynamically
  (by looking up the appropriate function in the vtable).

Neither of these features is implemented yet, but we do print out
qualified names for QualifiedDeclRefExprs as part of the AST printing.

- Fix bugs 3194, 3195: i128 load/stores produce correct code (although, we
  need to ensure that i128 is 16-byte aligned in real life), and 128 zero-
  extends are supported.
- New td file: SPU128InstrInfo.td: this is where all new i128 support should
  be put in the future.
- Continue to hammer on i64 operations and test cases; ensure that the only
  remaining problem will be i64 mul.

InputArg and UnknownArg.
 - Every argument now always corresponds to some option, which
   simplifies other code.

- 'Buffer' is now private and must be accessed via 'getBuffer()'.
   This paves the way for lazily mapping in source files on demand.
- Added 'getSize()' (which gets the size of the content without
   necessarily accessing the MemBuffer) and 'getSizeBytesMapped()'.
- Modifed SourceManager to use these new methods.  This reduces the
  number of places that actually access the MemBuffer object for a file
  to those that actually look at the character data.

These changes result in no performance change for -fsyntax-only on Cocoa.h.

AddPseudoTwoAddrDeps. This lets the scheduling infrastructure
avoid recalculating node heights. In very large testcases this
was a major bottleneck. Thanks to Roman Levenstein for finding
this!

As a side effect, fold-pcmpeqd-0.ll is now scheduled better
and it no longer requires spilling on x86-32.
