*	[ARM] Use Cortex-A57 sched model for Cortex-A72	Sam Parker	2018-10-25	1	-0/+1
\| \| \| \| \| \| \| \| \| \| \|	This mirrors what we already do for AArch64 as the cores are similar. As discussed in the review, enabling the machine scheduler causes more variations in performance changes so it is not enabled for now. This patch improves LNT scores by a geomean of 1.57% at -O3.

*	[ARM] Allow unrolling of multi-block loops.	Sam Parker	2017-10-23	1	-0/+316
\| \| \| \| \| \| \| \| \| \| \|	Before, loop unrolling was only enabled for loops with a single block. This restriction has been removed and replaced by: - allow a maximum of two exiting blocks, - a four basic block limit for cores with a branch predictor.

*	[ARM] Improve loop unrolling for Cortex-M	Sam Parker	2017-08-16	1	-92/+128
\| \| \| \| \| \| \| \| \| \| \|	- Set the default runtime unroll count to 4 and use the newly added UnrollRemainder option. - Create loop cost and force unroll for a cost less than 12. - Disable unrolling on Thumb1 only targets.

*	[ARM] Enable partial and runtime unrolling	Sam Parker	2017-07-25	2	-0/+213
	Enable runtime and partial loop unrolling of simple loops without calls on M-class cores. The thresholds are calculated based on whether the target is Thumb or Thumb-2. Differential Revision: https://reviews.llvm.org/D34619 llvm-svn: 308956
