Look for patterns of the form (store (load ...), ...) in which the two locations are known not to partially overlap. (Identical locations are OK.) These sequences are better implemented by MVC unless either the load or the store could use RELATIVE LONG instructions. The testcase showed that we weren't using LHRL and LGHRL for extload16, only sextloadi16. The patch fixes that too. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185919 91177308-0d34-0410-b5e6-96231b3b80d8
