PR target/109402: v850 (not v850e) variant of __muldi3() moves sp in reversed direction [PR109402]

muldi3 will deallocate stack space after the call to __save_r26_r31,
then re-allocate the space a short while later.  If an interrupt
occurs in that window, it can clobber items on the stack.

PR target/109402

* config/v850/lib1funcs.S (___muldi3): Remove unnecessary
stack manipulations.
