Shuxin Yang d3ae2866d1 This change is to implement following rules:
o. X/C1 * C2 => X * (C2/C1) (if C2/C1 is neither special FP nor denormal)
  o. X/C1 * C2 -> X/(C1/C2)   (if C2/C1 is either specical FP or denormal, but C1/C2 is a normal Fp)

     Let MDC denote multiplication or dividion with one & only one operand being a constant
  o. (MDC ± C1) * C2 => (MDC * C2) ± (C1 * C2)
     (so long as the constant-folding doesn't yield any denormal or special value)

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.
