dc406b8e92 IRgen: Move BitField LValues to just hold a reference to the CGBitFieldInfo. 
- Unfortunately, this requires some horrible code in CGObjCMac which always
   allocats a CGBitFieldInfo because we don't currently build a proper layout
   for Objective-C classes. It needs to be cleaned up, but I don't want the
   bit-field cleanups to be blocked on that.

d9c7c6568e Introduce a new kind of derived-to-base cast which bypasses the need for 
null checks, and make sure we elide null checks when accessing base class
members.

isInteger, we now have isFloatTy and isIntegerTy.  Requested by Chris!

40775003e6 Roll out ASTContext::getTypeSizeInChars(), replacing instances of 
"ASTContext::getTypeSize() / 8". Replace [u]int64_t variables with CharUnits
ones as appropriate. 

Also rename RawType, fromRaw(), and getRaw() in CharUnits to QuantityType, 
fromQuantity(), and getQuantity() for clarity.

would have a higher respect for its own code. This is getting old, is this

e96f1d3b2f More work on ScalarExprEmitter::EmitCastExpr: for every cast kind, either 
implement it explicitly or assert that it doesn't make sense for a scalar.
This caught a couple interesting issues: one, CK_BaseToDerivedMemberPointer
casts were getting silently miscompiled, and two, Sema was constructing some
strange implicit casts of type CK_UserDefinedConversion.

The change in SemaExprCXX makes sure the cast kinds are getting set correctly.

cb422f1dbe Use the more general Evaluate infrastructure for folding constant DeclRefs 
instead of checking explicitly for an EnumConstantDecl.  This folds references
to constant integer VarDecls, which has two benefits:

1. Slightly smaller emitted code from emitting a constant instead of a load,
and skipping emitting some constant globals.
2. Some code forgets to define static constant member variables; emitting a
load instead of the value in that case leads to a link error. (Such programs
are technically not well-formed, but in practice build with g++.)

using the new LLVM support for this.  This is temporarily hiding
behind horrible and ugly #ifdefs until the time when the optimizer
is stable (hopefully a week or so).  Until then, lets make it "opt in" :)
