Use some less-known grep flags to avoid the for loop in
check-unused-bailouts.sh, speeding it up considerably.
Before:
$ time tools/check-unused-bailouts.sh >/dev/null
real 0m14.717s
user 0m6.968s
sys 0m7.128s
After:
$ time tools/check-unused-bailouts.sh >/dev/null
real 0m0.514s
user 0m0.480s
sys 0m0.028s
