[clang] Remove unnecessary -O1 from clang command. (PR #190417)

[Peter Collingbourne via cfe-commits]

https://github.com/pcc created https://github.com/llvm/llvm-project/pull/190417

It is generally inappropriate to pass -O flags to IRGen tests because
it makes them sensitive to optimizer behavior. #186548 makes a change to
optimizer behavior that would cause this test to fail without this change.
