xtensa: Tweak some widen multiplications
umulsidi3 is faster than umuldi3 even if library call, and is also
prerequisite for fast constant division by multiplication.
gcc/ChangeLog:
* config/xtensa/xtensa.md (mulsidi3, umulsidi3):
Split into individual signedness, in order to use libcall
"__umulsidi3" but not the other.
(<u>mulhisi3): Merge into one by using code iterator.
(<u>mulsidi3, mulhisi3, umulhisi3): Remove.
