Chris Lattner 9ec975a4b5 fix and concisify intinsic lowering for ctpop. Unfortunately, this code 
looks completely untested. :(

Chris Lattner 06bbeb646f Fix the last remaining bug preventing us from switching the X86 BE over 
from the simple isel to the pattern isel.  This forces inserted libcalls
to serialize against other function calls, which was breaking
UnitTests/2005-05-12-Int64ToFP.  Hopefully this will fix issues on other
targets as well.

Andrew Lenharth 0409e1e6d5 Legalize for CTLZ generates a ctpop, but this ctpop is not expanded. 
This is bad.  It is generated if you are ctlz a type that is not
legal for the arch (aka ctlz of bytes on alpha legalize fine).

Duraid Madina 25163d8d60 add the popcount instruction and support this in the isel 
the primary user of this will probably end up being find-first-set-bit/find-

Chris Lattner 70ea07cfd2 Implement READPORT/WRITEPORT, implementing the last X86 regression tests 
that were failing with the pattern selector.  Note that the support that
existed in the simple selector was clearly broken in several ways though
(which has also been fixed).
