[test] Fix loop-micro-op-buffer-size-t99.ll under NPM

The NPM runs loop passes on loops in forward program order instead of
the legacy PM's reverse program order, causing some debug output to be
in a different order.

[AArch64] Improve loop unrolling performance on Cavium T99

This patch improves performance on Cavium T99 as shown here (libquantum 0.2.4):

https://docs.google.com/spreadsheets/d/1Lo1o2E1NjrpkwS7DvYYWsiVvPdd93h7KBaqeptMrZPY/edit?usp=sharing

By increasing the LoopMicroOpsBufferSize in the Cavium T99 Scheduler file,
loop unrolling becomes more aggressive. This helps performance on T99.

Test case included.
