[CodeGen] Don't assume that fixed stack objects are aligned in a stack-realigned function.
Summary:
After we make the adjustment, we can assume that for local allocas, but
not for stack parameters, the return address, or any other fixed stack
object (which has a negative offset and therefore lies prior to the
adjusted SP).
Fixes PR26662.
