Move CR0 caching into the standard register caching mechanism in order to take advantage of the availability checks provided by regs_avail. This avoids multiple VMREADs in the (uncommon) case where kvm_read_cr0() is called multiple times in a single VM-Exit, and more importantly eliminates a kvm_x86_ops hook, saves a retpoline on SVM when reading CR0, and squashes the confusing naming discrepancy of "cache_reg" vs. "decache_cr0_guest_bits". No functional change intended.
