b4d2e502 - [LLVM] Use `reportFatalUsageError` for LTO usage errors (#140955)

[LLVM] Use `reportFatalUsageError` for LTO usage errors (#140955) Usage errors in `LTOBackend.cpp` were previously, misleadingly, reported as internal crashes. This PR updates `LTOBackend.cpp` to use `reportFatalUsageError` for reporting usage-related issues. LLVM Issue: https://github.com/llvm/llvm-project/issues/140953 Internal Tracker: TOOLCHAIN-17744
