eventually get an option to turn this off, but it is nice for looking at 
statistics.  For example, the types block now prints:

BLOCKNAME and SETRECORDNAME.  This allows a bitcode
file to be self describing with pretty names for 
records and blocks in addition to numbers.  This
enhances llvm-bcanalyzer to use this to print prettily.

  - Deal with the Receiver/ClassInfo shared storage in ObjCMessageExpr
  - Implement PCH support for ImplicitParamDecl
  - Fix the handling of the body of an ObjCMethodDecl
  - Several cast -> cast_or_null fixes
  - Make Selector::getIdentifierInfoForSlot work for 1-argument, NULL
  selectors.
  - Make Selector::getAsString() work with NULL selectors.
  - Fix the names of VisitObjCAtCatchStmt and VisitObjCAtFinallyStmt
  in the PCH reader and writer; these were never getting called.

At this point, all of the pch-test tests pass for C and Objective-C.

state out of the BitstreamReader class into a BitstreamCursor class.
Doing this allows the client to have multiple cursors into the same
file, each with potentially different live block stacks and
abbreviation records.

This could definitely use some cleanup, but I don't really want to mess 
with the anonymous union/struct code.

Now we produce:

necessary and iterate until all types and declarations have been
written. This reduces the Cocoa.h PCH file size by about 4% (since we
don't write types we don't need), and fixes problems where writing a
declaration generates a new type.

This doesn't seem to have any impact on performance either way.

 - This can be used to supply a default value for -std=; the idea is
   that this can be used in conjunction with CCC_ADD_ARGS or
   QA_OVERRIDE_GCC3_OPTIONS to change the default without having to
   modify the build system.
