eeeaf45bba 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.

b9062e56cf 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-
last-set-bit, which i'll get around to...

d96aea21d7 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).
