[PATCH] D50964: [Sparc] Use ANDN instead of AND if constant can be encoded more efficiently

[Daniel Cederman via Phabricator via llvm-commits]

dcederman added a comment.

When I was testing the code I saw that it sometimes generated two versions of the same constant, one with the single SETHI with the complement form, and one with the standard SETHI/ORri pair. So I added the hasOneUse() part to prevent the case when a constant is encoded using three instructions instead of just one or two.
