Change Details

The old CPU model only had MLA->MLA forwarding. I added some missing MUL->MLA read advances and a missing absolute diff accumulator read advance according to the Cortex A57 Software Optimization Guide. Also added missing schedules for ASIMD shift by immed basic, and ASIMD shift by register, basic, D-form. The patch improves performance in EEMBC benchmark and causes no significant regressions (none in SPEC).

The patch improves performance in EEMBC rgbyiqv2 by about 6%-7% and spec2006/milc by 8% (repeated runs on multiple devices), causes no significant regressions (none in SPEC).
