Changes in directory llvm/lib/Target/IA64:

IA64InstrInfo.td updated: 1.12 -> 1.13
IA64ISelPattern.cpp updated: 1.37 -> 1.38

Log message:

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...
