i386: Fix up x86 atomic_bit_test* expanders for !TARGET_HIMODE_MATH [PR103205]
With !TARGET_HIMODE_MATH, the OPTAB_DIRECT expand_simple_binop fail and so
we ICE. We don't really care if they are done promoted in SImode instead.

PR target/103205
* config/i386/sync.md (atomic_bit_test_and_set<mode>,
atomic_bit_test_and_complement<mode>,
atomic_bit_test_and_reset<mode>): Use OPTAB_WIDEN instead of
OPTAB_DIRECT.
* gcc.target/i386/pr103205.c: New test.
