[LLVM] [X86] Fix integer overflows in frame layout for huge frames (#101840)
Fix 32-bit integer overflows in the X86 target frame layout when dealing
with frames larger than 4gb. When this occurs, we'll scavenge a scratch
register to be able to hold the correct stack offset for frame locals.
This completes reapplying #84114.
Fixes #48911
Fixes #75944
Fixes #87154
