Using an invalid -O falls back on -O3 instead of an error
Summary:
Currently with clang:
$ clang -O20 foo.c
error: invalid value '20' in '-O20'
With the patch:
$ clang -O20 foo.c
warning: optimization level '-O20' is unsupported; using '-O3' instead.
1 warning generated.
This matches the gcc behavior (with a warning added)
Pass all tests:
Testing: 0 .. 10.. 20.. 30.. 40.. 50.. 60.. 70.. 80.. 90..
Testing Time: 94.14s
Expected Passes : 6721
Expected Failures : 20
Unsupported Tests : 17
