target-i386: Remove POPCNT from qemu64 and qemu32 CPU models

POPCNT is not available on Penryn and older and on Opteron_G2 and older,
and we want to make the default CPU runnable in most hosts, so it won't
be enabled by default in KVM mode.

We should eventually have all features supported by TCG enabled by
default in TCG mode, but as we don't have a good mechanism today to
ensure we have different defaults in KVM and TCG mode, disable POPCNT in
the qemu64 and qemu32 CPU models entirely.
