deduction. Unify all of the looping over template arguments for
deduction purposes into a single place, where argument pack expansion
occurs; this is also the hook for deducing from pack expansions, which
itself is not yet implemented.

For now, at least we can handle a basic "count" metafunction written
with variadics. See the new test for the formulation that works.

wrong but suboptimal).  Also correct a typo (A <-> B) in the second
chunk.

if both A op B and A op C simplify.  This fires fairly often but doesn't
make that much difference.  On gcc-as-one-file it removes two "and"s and
turns one branch into a select.

loads properly.  We miscompiled the testcase into:

_test:                                  ## @test
	movl	$128, (%rdi)
	movzbl	1(%rdi), %eax
	ret

Now we get a proper:

_test:                                  ## @test
	movl	$128, (%rdi)
	movsbl	(%rdi), %eax
	movzbl	%ah, %eax
	ret

This fixes PR8757.

This change is necessary when the variable is a const reference and we need
the l-value of the construct expr.  After that, when binding the variable,
recover the lazy compound value when the variable is not a reference.

In Environment, use the value of a no-op cast expression when it has one.
Otherwise, blast-through it.

Previously designated anonymous fields were found via name lookup. This redesign uses the fact that an IndirectFieldDecl declaration will always follow an anonymous implicit field to remove the special case of name lookup.

SectionLoadList.cpp (ResolveLoadAddress): Don't assert on an

The unwinder may be passing in invalid addresses on the final
stack frame and the assert is a problem.
