wide-int.cc has skipped longlong.h under clang since PR bootstrap/61146,
because clang rejected the casts on asm output operands in it.
longlong.h now builds with clang, so drop the check. A GCC built by
clang without bootstrapping, such as a cross compiler or a compiler
hosted on macOS, then uses umul_ppmm from longlong.h in wi::mul_internal
instead of the generic multiplication loop.
gcc/ChangeLog:
PR bootstrap/61146
* wide-int.cc: Include longlong.h with clang too.
