Change Details

Added some accumulate op to accumulate op, and non-accumulate op (e.g. mul, shift) to accumulate op forwarding according to the Cortex A57 Software Optimization Guide. Old model only had mla->mla forwarding.

The old CPU model only had MLA->MLA forwarding. I added some more accumulate op to accumulate op, and non-accumulate op (e.g. MUL, shift) to relevant accumulate op (e.g. MLA, SRA) forwarding according to the Cortex A57 Software Optimization Guide. The patch improves performance in some internal benchmarks and causes no significant regressions (none in SPEC).
