LLVM backend for 6502
34288d885e
Now that we can fully specify extload legality, we can declare them legal for the PMOVSX/PMOVZX instructions. This for instance enables a DAGCombine to fire on code such as (and (<zextload-equivalent> ...), <redundant mask>) to turn it into: (zextload ...) as seen in the testcase changes. There is one regression, in widen_load-2.ll: we're no longer able to do store-to-load forwarding with illegal extload memory types. This will be addressed separately.
