Fix PR5279 - don't sliently drop alignment information on stores of types that have alignment less than the natural alignment of the type when it comes from a typedef.

Make EmitAggregateCopy take an alignment argument.  Make EmitFinalDestCopy pass in the correct alignment when known.

The test includes a FIXME for a related case involving calls; it's a bit more complicated to fix because the RValue class doesn't keep track of alignment.

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
