Cuong Manh Le 00bee6d9a4 cmd/compile/internal/typebits: relax alignment check
Now we have 8-byte alignment types on 32-bit system, so in some rare
case, e.g, generated wrapper for embedded interface, the function
argument may need more than 4 byte alignment. We could pad somehow, but
this is a rare case which makes it hard to ensure that we've got it right.

So relaxing the check for argument and return value region of the stack.

Fixes #54991
