Chris Lattner 2539e33893 More than just loads can read from memory: readonly calls like strlen
also need to be checked for memory modifying instructions before we
can sink them.  THis fixes the second half of PR2297.

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.
