Fix MIPS call-clobbered-*.c tests
Jeff pointed out that gcc.target/mips/call-clobbered-4.c started
failing after the function-abi series. This is because IRA used
to treat partly call-clobbered registers as hard conflicts and
so wouldn't consider them for -fcaller-saves. Now that we treat
call clobbers the same way regardless of where they come from,
we can use $f21 as a caller-save register. This in turn means
that -Os is no longer a special case in call-clobbered-3.c.
(The new code is the same size as the old code.)
