Sema: defer stores to inferred allocs
...
This lets us generate the store with knowledge of the type to be stored.
Therefore, we can avoid generating garbage Air with stores through
pointers to comptime-only types which backends cannot lower.

Sema: allow dereferencing ill-defined pointers to zero-bit types at comptime
...
It doesn't matter if a pointer to a zero-bit (i.e. OPV) type is
undefined or runtime-known; we still know the result of the dereference
at comptime. Code may use this, for instance, when allocating zero-bit
types: `@as(*void, undefined)` is entirely reasonable to use at runtime,
since we know the pointer will never be accessed, thus it should be
valid at comptime too.

Sema: allow comptime mutation of multiple array elements
...
Previously, if you had a pointer to multiple array elements and tried to
write to it at comptime, it was incorrectly treated as a pointer to one
specific array value, leading to an assertion down the line. If we try
to mutate a value at an elem_ptr larger than the element type, we need
to perform a modification to multiple array elements.
This solution isn't ideal, since it will result in storePtrVal
serializing the whole array, modifying the relevant parts, and storing
it back. Ideally, it would only take the required elements. However,
this change would have been more complex, and this is a fairly rare
operation (nobody ever ran into the bug before after all), so it doesn't
matter all that much.
