Jim Grosbach f0d25117c6 ARM VFP add encoding of the bitcount to fixed-point<-->floating point. insns. 
The value from the operands isn't right yet, but we weren't encoding it at
all previously. The parser needs to twiddle the values when building the
instruction.

Partial for: rdar://10558523

Douglas Gregor 0475cd88c9 If we end up merging an Objective-C class with an existing Objective-C 
class that comes from a different module file, make sure that we load
all of the pending declarations for the original declaration.

Jim Ingham ef65160016 Improve the x86_64 return value decoder to handle most structure returns. 
Switch from GetReturnValue, which was hardly ever used, to GetReturnValueObject
which is much more convenient.
Return the "return value object" as a persistent variable if requested.

Chandler Carruth b024aa021d Make the unreachable probability much much heavier. The previous 
probability wouldn't be considered "hot" in some weird loop structures
or other compounding probability patterns. This makes it much harder to
confuse, but isn't really a principled fix. I'd actually like it if we
could model a zero probability, as it would make this much easier to
reason about. Suggestions for how to do this better are welcome.

Douglas Gregor 022857e03d When deserializing an Objective-C class, check whether we have another 
declaration of that same class that either came from some other module
or occurred in the translation unit loading the module. In this case,
we need to merge the two redeclaration chains immediately so that all
such declarations have the same canonical declaration in the resulting
AST (even though they don't in the module files we've imported).

Focusing on Objective-C classes until I'm happy with the design, then
I'll both (1) extend this notion to other kinds of declarations, and
(2) optimize away this extra checking when we're not dealing with
modules. For now, doing this checking for PCH files/preambles gives us
better testing coverage.
