PR target/82981
* internal-fn.c: Include gimple-ssa.h, tree-phinodes.h and
ssa-iterators.h.
(can_widen_mult_without_libcall): New function.
(expand_mul_overflow): If only checking unsigned mul overflow,
not result, and can do efficiently MULT_HIGHPART_EXPR, emit that.
Don't use WIDEN_MULT_EXPR if it would involve a libcall, unless
no other way works. Add MULT_HIGHPART_EXPR + MULT_EXPR support.
(expand_DIVMOD): Formatting fix.
* expmed.h (expand_mult): Add NO_LIBCALL argument.
* expmed.c (expand_mult): Likewise. Use OPTAB_WIDEN rather
than OPTAB_LIB_WIDEN if NO_LIBCALL is true, and allow it to fail.
* gcc.target/mips/pr82981.c: New test.
