  -----------
  [UTC] Strip only standalone positional %s in update_test_checks.py (#221153)

Previously, update_test_checks.py used tool_cmd_args.replace("%s", "")
to strip the input file when passing the IR via stdin. However, this
blindly removed "%s" from any option argument, leaving an empty value
(e.g., -lowertypetests-read-summary=).

Update the argument stripping to only remove standalone positional
"< %s" or "%s", preserving option arguments with "%s" values so they can
be expanded via common substitutions.

This enables update_test_checks.py to work for tests such as
llvm/test/Transforms/LowerTypeTests/cfi-jumptable-hotness-summary.ll,
which passes -lowertypetests-read-summary=%s on the RUN line.
