When mangling member-expressions, skip implicit accesses of anonymous union

objects. This is consistent with GCC's behavior. Patch by Tomasz Miąsko!

AST: Mangle cast expression encoding more accurately
...
Don't mangle all casts in expressions as "cv", use the appropriate
encoding which corresponds to a specific cast.
This fixes PR21034.

A follow-up patch will improve the storage usage of these
fields; here I've just done the lazy thing.

fix PR5179 and correctly fix PR5831 to not miscompile.
...
The X86-64 ABI code didn't handle the case when a struct
would get classified and turn up as "NoClass INTEGER" for
example. This is perfectly possible when the first slot
is all padding (e.g. due to empty base classes). In this
situation, the first 8-byte doesn't take a register at all,
only the second 8-byte does.
This fixes this by enhancing the x86-64 abi stuff to allow
and handle this case, reverts the broken fix for PR5831,
and enhances the target independent stuff to be able to
handle an argument value in registers being accessed at an
offset from the memory value.
This is the last x86-64 calling convention related miscompile
that I'm aware of.

iterations of this patch gave explicit template instantiation
link-once ODR linkage, which permitted the back end to eliminate
unused symbols. Weak ODR linkage still requires the symbols to be
generated.
