Check early if this is an unsupported opcode, so that we can avoid needlessly instantiating the base register in some cases.

This may eliminate some uses of the spilled registers, and we don't want to

This fixes a bunch of errors when compiling MSVC header files with the -DDLL flag.

when the resolution took place due to a single template specialization
being named with an explicit template argument list. In this case, the
"resolution" doesn't take into account the target type at all, and
therefore can take place for functions, static member functions, and
*non-static* member functions. The latter weren't being properly checked
and their proper form enforced in this scenario. We now do so.

The result of this last form slipping through was some confusing logic
in IsStandardConversion handling of these resolved address-of
expressions which eventually exploded in an assert. Simplify this logic
a bit and add some more aggressive asserts to catch improperly formed
expressions getting into this routine.

Finally add systematic testing of member functions, both static and
non-static, in the various forms they can take. One of these is
essentially PR9563, and this commit fixes the crash in that PR. However,
the diagnostics for this are still pretty terrible. We at least are now
accepting the correct constructs and rejecting the invalid ones rather
than accepting invalid or crashing as before.

The instruction to be rematerialized may not be the one defining the register
that is being spilled. The traceSiblingValue() function sees through sibling

    f = vmlal_u8(f, vget_low_u8(s),  c);

Add workaround for Sema issue found in <rdar://problem/9188004>, which leads to an assertion failure in the uninitialized variables analysis.  The problem is that Sema isn't properly registering a variable in a DeclContext (which -Wuninitialized relies on), but
my expertise on the template instantiation logic isn't good enough to fix this problem for real.  This patch worksaround the
problem in -Wuninitialized, but we should fix it for real later.
