Implicitly expand argument packs when performing template argument
...
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.

Add a generic expansion transform: A op (B op' C) -> (A op B) op' (A op C)

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.

Fix a bug in ReduceLoadWidth that wasn't handling extending

loads properly. We miscompiled the testcase into:
_test: ## @test

movsbl (%rdi), %eax
movzbl %ah, %eax

After inlining the CXXConstructExpr, bind the temporary object region to it.

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.
