c-family: One more 40752 tweak for unsigned char.
My last patch didn't fix all the failures on unsignd char targets. We were
missing one warning because by suppressing -Wsign-conversion for the second
operand of + we missed an overflow that we want to warn about, and we
properly don't warn about unsigned / or %.
PR testsuite/93391 - PR 40752 test fails with unsigned plain char.
* c-warn.c (conversion_warning): Change -Wsign-conversion handling.
* lib/target-supports.exp (check_effective_target_unsigned_char):
New.
