* tree-ssa-forwprop.c (simplify_rotate): Only recognize
the (-Y) & (B - 1) variant if OP is |.
* expmed.c (expand_shift_1): For rotations by const0_rtx just
return shifted. Use (-op1) & (prec - 1) as other_amount
instead of prec - op1.
* c-c++-common/rotate-1.c: Add 32 tests with +.
* c-c++-common/rotate-1a.c: Adjust.
* c-c++-common/rotate-2.c: Add 32 tests with +, expect
only 48 rotates.
* c-c++-common/rotate-2b.c: New test.
