This pass runs before COPY instructions are passed to copyPhysReg, so we simply
translate COPY to the proper pseudo instruction. Note that copyPhysReg does not
handle floating point stack copies.

Once COPY is used everywhere, this can be cleaned up a bit, and most of the
pseudo instructions can be removed.

Introduce PCHReader::GetTranslationUnitDecl() and use it instead of ReadDeclRecord when initializing.

ReadDeclRecord would hit assertion if the translation unit declaration was already loaded during
IdentifierInfo initialization.

EXTRACT_SUBREG no longer appears as a machine instruction. Use COPY instead.

Add isCopy() checks in many places using isMoveInstr() and isExtractSubreg().
The isMoveInstr hook will be removed later.

For TagType and TemplateSpecializationType, isDependent calculation may be invalid because some decls that the
calculation is using may still be initializing.
Thus, store the isDependent flag to PCH and restore directly to Type.

This optimization could be extended to take non-const C1 and C2 but we better
stay conservative to avoid code size bloat for now.

list in a diagnostic group so it can be turned on and off. A terrifying amount
of code, including large chunks of open source code, still do this so it's
important to be able to suppress it when necessary.

Doug, is this a reasonable compromise? I'd lean toward making it a normal
extension, but I don't feel strongly as long as we can turn the warnings off.
