Primitive bitwise operations on Int#

[jstolarek]

During recent work I found a need for primitive bitwise operations that work on Int# type. Currently existing and#, or#, not# and xor# PrimOps work on Word#, which requires writing explicit conversions using int2Word# and word2Int#. It would be most helpful to have equivalent andI#, orI#, notI# and xorI# PrimOps.

Could you please separate out the whitespace changes into a separate patch?

Adds primitive bitwise operatons on Int#

[jstolarek]

Whoops. Sorry about that. I've recently set up my Emacs to remove trailing whitespaces upon saving. A good thing to do, but only assuming that everyone else in the team does that. Anyway, I've uploaded the fixed patch.

Pushed, thanks!

It looks that patch for the Testsuite was not merged. Reopening.
