llvm dev - May 2014 - [LLVMdev] Is it ok to nuke fpcmp and llvm-PerfectShuffle utils?

It is building using configure + make. In good old days the perfect
shuffle tables for PPC were generated through the normal build process
like .td files. However, this was pretty useless - they do not change
and thus perfectshuffle was excluded from the build process.

Agreed, but even if it is not built by default, we should have build rules for
it; and given that more users and developers are moving to cmake-based builds,
we should have build rules in cmake too.

I've added it to CMake build in r208225.

What about fpcmp binary? Does anyone still use it?
