Dan Gohman 4f833d4351 On 64-bit targets, change 32-bit getelementptr indices to be 64-bit 
getelementptr indices, inserting an explicit cast if necessary.
This helps expose the sign-extension operation to other optimizations.

This directory contains test cases for the instcombine transformation.  The
dated tests are actual bug tests, whereas the named tests are used to test
for features that the this pass should be capable of performing.
