KVM: x86: Add helpers to query individual CR0/CR4 bits
Add helpers to check if a specific CR0/CR4 bit is set to avoid a plethora
of implicit casts from the "unsigned long" return of kvm_read_cr*_bits(),
and to make each caller's intent more obvious.
Defer converting helpers that do truly ugly casts from "unsigned long" to
"int", e.g. is_pse(), to a future commit so that their conversion is more
isolated.
Opportunistically drop the superfluous pcid_enabled from kvm_set_cr3();
the local variable is used only once, immediately after its declaration.
