Revert "[LLVM] [X86] Fix integer overflows in frame layout for huge frames (#101840)"

This casuses assertion failures targeting 32-bit x86:

  lib/Target/X86/X86RegisterInfo.cpp:989:
  virtual bool llvm::X86RegisterInfo::eliminateFrameIndex(MachineBasicBlock::iterator, int, unsigned int, RegScavenger *) const:
  Assertion `(Is64Bit || FitsIn32Bits) && "Requesting 64-bit offset in 32-bit immediate!"' failed.

See comment on the PR.

> 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
