  Recommit: "[llvm-exegesis] Improve error reporting in Assembler.cpp"

Summary: Commit 63bb9fee525f8f29fd9c2174fa7f15573c3d1fd7 was reverted in
7603bfb4b0a6a90137d47f0182a490fe54bf7ca3 because it broke builds that treat
warnings as errors.
This commit updates the calls to `assembleToStream()` in tests to check that
the return value is valid.

Original commit message:

Followup to D74084.
Replace the use of `report_fatal_error()` with returning the error to
`llvm-exegesis.cpp` and handling it there.
