We're hitting asserts after this when targeting 32-bit x86:

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 https://crbug.com/361106069#comment4 for a reproducer.

Reverting for now.
