Dan Gohman 9737a63ed8 Change these tests to feed the assembly files to opt directly, instead 
of using llvm-as, now that opt supports this.

Dan Gohman bc0278400c Teach instcombine's visitLoad to scan back several instructions 
to find opportunities for store-to-load forwarding or load CSE,
in the same way that visitStore scans back to do DSE. Also, define
a new helper function for testing whether the addresses of two
memory accesses are known to have the same value, and use it in
both visitStore and visitLoad.

These two changes allow instcombine to eliminate loads in code
produced by front-ends that frequently emit obviously redundant
addressing for memory references.
