Craig Topper 0d830ff7bf [InstCombine] Use commutable matchers and m_OneUse in visitSub to shorten code. Add missing test cases.
In one case I removed commute handling for a multiply with a constant since we'll eventually get the constant on the right hand side.

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.
