  Changed paths:
    M llvm/lib/Target/X86/X86ISelDAGToDAG.cpp
    A llvm/test/CodeGen/X86/dag-large-offset.ll
    M llvm/test/CodeGen/X86/xor-lea.ll

  Log Message:
  -----------
  [X86] Don't fold very large offsets into addr displacements during ISel  (#121678)

Doing so can cause the resulting displacement after frame layout to
become inexpressible (or cause over/underflow currently during frame
layout).

Fixes the error reported in
https://github.com/llvm/llvm-project/pull/101840#issuecomment-2306975944.
