5f2a0d17ab Fix a really horrible problem that causes the JIT to miscompile any program
that use 64-bit integers on 32-bit hosts.

e84f776b5d Necessary changes to codegen cttz efficiently on PowerPC
1. Teach LegalizeDAG how to better legalize CTTZ if the target doesn't have
   CTPOP, but does have CTLZ
2. Teach PPC32 how to do sub x, const -> add x, -const for valid consts
3. Teach PPC32 how to do and (xor a, -1) b -> andc b, a
4. Teach PPC32 that ISD::CTLZ -> PPC::CNTLZW

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).
