IRgen: Add CreateMemTemp, for creating an temporary memory object for a particular type, and flood fill. - CreateMemTemp sets the alignment on the alloca correctly, which fixes a great many places in IRgen where we were doing the wrong thing.

- This fixes many many more places than the test case, but my feeling is we need to audit alignment systematically so I'm not inclined to try hard to test the individual fixes in this patch. If this bothers you, patches welcome!

At the moment the inlinehint attribute is ignored by the Inliner unless you
pass a -respect-inlinehint option.  This will soon be the default.

The inlinehint attribute is set if the inline keyword is explicitly specified
on any declaration.

The standard actually says that such references should have internal linkage,
but gcc doesn't do that, so we probably can't get away with it.

If a constructor throws an exception we need to execute the destructors for all fully constructed members. Fixes ctor_dtor_count.cpp in the test suite.

follows (as conservatively as possible) gcc's current behavior:  attributes
written on return types that don't apply there are applied to the function
instead, etc.  Only parse CC attributes as type attributes, not as decl attributes;
don't accepet noreturn as a decl attribute on ValueDecls, either (it still
needs to apply to other decls, like blocks).  Consistently consume CC/noreturn
information throughout codegen;  enforce this by removing their default values
in CodeGenTypes::getFunctionInfo().

Also, simplify EmitParmDecl and don't worry about using Decl::getNameAsString.
