New Revision: 109120

URL: http://llvm.org/viewvc/llvm-project?rev=109120&view=rev
Log:
LLVM now supports constant expressions with multiple uses.  When replacing uses
of an original function with a clone, scan through all operands of a constant
and replace those that are the old function.
This fixes a problem transforming 254.gap on Linux.
