First cut at setting attributes for functions and calls; this puts us
much closer to passing the gcc struct layout tests.
It might be possible to refactor this a bit, but I'm not sure there's
actually enough common code for that to be useful.
To get the calling convention completely correct, a bit of
platform-specific code is necessary even for x86-Linux. On x86-Linux, the
alignment of function parameters is extremely strange; as far as I can tell,
it's always 4 except for SSE vectors or structs containing SSE vectors. I'm
continuing to investigate this.

This fix involved tightening up needToScanForQualifiers(), which predated ObjCQualifiedIdType.
It also includes a minor tweak to the code that searches for the beginning of the qualified type. If the AST contained the correct beginning of the declaration (i.e. the beginning of the declaration specifiers), this code would be more robust. Since it doesn't, we apply an adhoc heuristic. Note that DeclSpec contains this info...we just don't propagate it to the AST (at present).

Allow the type of a global to be different from the type of its

general union initializations; for example, an array of unions involving
pointers has to be turned into a struct because the elements can have
incompatible types.

definitions is all in EmitGlobalVarInit.
