Hi, For PR96866, when gcc print asm code for modifier "%a" which requires an address operand, while the operand is with the constraint "X" which allow non-address form. An error message would be reported to indicate the invalid asm operands. Bootstrap pass on ppc64{,le}. Is this ok for trunk?

[PATCH] Don't reduce estimated unrolled size for innermost loop.

As testcase in the PR, O3 cunrolli may prevent vectorization for the innermost loop and increase register pressure. The patch removes the 1/3 reduction of unr_insn for innermost loop for UL_ALL. ul != UR_ALL is needed since some small loop complete unrolling at O2 relies the reduction.
