*	[ARM] LE support in ConstantIslands	Sam Parker	2019-09-17	1	-0/+201
	The low-overhead branch extension provides a loop-end 'LE' instruction that performs no decrement nor compare, it just jumps backwards. This patch modifies the constant islands pass to try to insert LE instructions in place of a Thumb2 conditional branch, instead of shrinking it. This only happens if a cmp can be converted to a cbn/z and used to exit the loop. Differential Revision: https://reviews.llvm.org/D67404 llvm-svn: 372085
