I've added a movti expander to sh.md, and found a regression for -m4 -ml
on simd-1.c with optimization options -O1, -O2, -O3 and -Os .
I've foun that a output reload address was being overwritten by
a secondary output reload.
The secondary output reload had RELOAD_FOR_OUTPUT_ADDRESS, and the
address reload had RELOAD_FOR_OUTADDR_ADDRESS, both for the same
operand. In the absence of a seond RELOAD_FOR_OUTPUT_ADDRESS
reload, these types are not supposed to conflict. The output
address reload should have used RELOAD_FOR_OUTPUT_ADDRESS.
