codegen: fix taking the address of a zero-bit field in a zero-bit struct
...
Normally when we want a pointer to the end of a struct we just add 1 to
the struct pointer. However, when it is a zero-bit struct, the pointer
type being used during lowering is often a dummy pointer type that
actually points to a non-zero-bit type, so we actually want to add 0
instead, since a zero-bit struct begins and ends at the same address.

llvm: fix use of invalid alignment
...
* Initialize `big_align` with 1 as 0 is not a valid alignment.
* Add an assert to `alignForwardGeneric` to catch this issue earlier.
* Refactor valid alignment checks to call a more descriptive function.

llvm: fix lowering pointer to final zero-width field of a comptime value
...
* Handle a `null` return from `llvmFieldIndex`.
* Add a behavior test to test this code path.
* Reword this test name, which incorrectly described how pointers to
zero-bit fields behave, and instead describe the actual test.

CBE: defer invariant local reuse in loops
...
When a local defined outside a loop dies inside the loop, it can still
be needed on subsequent loop iterations, so reuse of the local must be
deferred until after the loop ends. This causes behavior tests to pass.
