[AMDGPU] expand-fp: always report modifications (#163153)

frederik-h · web-flow · commit 8cc862ce3bd5 · 2025-10-13T15:21:02.000Z
The last change to the pass in PR #158588 lost the assignment to the
"Modified" variable for one of the pass optimizations.

Add it back. This fixes the test failure in
`CodeGen/AMDGPU/itofp.i128.bf.ll` (in a
`LLVM_ENABLE_EXPENSIVE_CHECKS=ON` build).
