Sanjay Patel 2aa471bd92 [InstCombine] remove zext-of-icmp fold that may conflict with other folds
This bit-hack transform would cause the new test to infinite loop
after 21d3871b7c90f85b3ae.

The deleted transform has existed for a very long time,
but the profitable parts appear to be handled by other
folds now. This fold could replace 2 instructions with
4 instructions, so it was always in danger of going
overboard.

No tests regress by removing the whole thing.

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.
