AVR: Speed up __umulhisi3 for small devices with MUL.

__umulhisi3 had an "rcall 1f" to save 6 bytes, which is an unreasonable
size gain vs. cycle cost.  Just use the same code on all devices with MUL,
irrespective of program memory size.

libgcc/
* config/avr/lib1funcs.S (__umulhisi3) [Have MUL]: Reduce call
depth by 1.
