*	Optimize zext on PPC64.	Hal Finkel	2012-08-28	1	-0/+11
	The zeroextend IR instruction is lowered to an 'and' node with an immediate mask operand, which in turn gets legalised to a sequence of ori's & ands. This can be done more efficiently using the rldicl instruction. Patch by Tobias von Koch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162724 91177308-0d34-0410-b5e6-96231b3b80d8
