mutable member and a constant initializer. We'd previously promoted such
variables to global constants, resulting in nasal demons if the mutable member
was modified.

This is only a temporary fix. The subtle interplay between isConstantInitializer
and CGExprConstant is very bug-prone; there are some other issues in this area
which I will be addressing in subsequent, more major reworking of this code.

When we're passing a vector with an illegal type through memory on x86-64, use byval so we're sure the backend does the right thing.  Fixes va_arg with illegal vectors and an obscure ABI mismatch with __m64 vectors.

serialization::Module to serialization::ModuleFile to side-step the
annoying naming conflict. Prune a bunch of ModuleMap.h includes that
are no longer needed (most files only needed the Module type).

The new metadata are method @encode strings with additional data.

1. Each Objective-C object is marked with its class name and protocol names.
The same is done for property @encode already.

2. Each block object is marked with its function prototype's @encoding. For
example, a method parameter that is a block object that itself returns void
and takes an int would look like:
    @?<v@?i>

These new method @encode strings are stored in a single array pointed to by structs protocol_t and objc_protocol_ext.

Correct the code generation for function arguments of vec3 types on x86_64 when they are greater than 128 bits. This was incorrectly coercing things like long3 into a double2.

This would reduce the number of useful declarations in
CGTemporaries.cpp to one.  Since CodeGenFunction::EmitCXXTemporary
does not deserve its own file, move it to CGCleanup.cpp and delete
CGTemporaries.cpp.
