Description of UFR feature:

Required in MIPS32r5 if floating point is implemented and user-mode FR
switching is supported. The UFR register allows user-mode to clear StatusFR
by executing a CTC1 to UFR with GPR[0] as input, and read StatusFR by
executing a CFC1 to UFR.

helper_ctc1 has been extended with an additional parameter rt to check
requirements for UFR feature.
Definition of mips32r5-generic has been modified to include support for UFR.

The ae2810c4 patch introduced
optimization for ram_list.dirty_memory update. However it can only
work correctly if hpratio is 1 as the @bitmap parameter stores 1 bits
per system page size (may vary, 4K or 64K on PPC64) and
ram_list.dirty_memory stores 1 bit per TARGET_PAGE_SIZE
(which is hardcoded to 4K).

This fixes hpratio!=1 case to fall back to the slow path.

The VMSTATE_STRUCT_POINTER macros are a bit odd in that they
must be passed an argument "FooType *" rather than just taking
the FooType. They're only used in one place, so it's easy to
tidy this up. This also lets us use the macro to replace the
hand-rolled VMSTATE_PTIMER.

The compiler is already able to eliminate the kvm_arch_get_supported_cpuid()
calls in kvm_cpu_fill_host() and filter_features_for_kvm(), so we can
eliminate the CONFIG_KVM #ifdefs there.

Also, kvm_cpu_fill_host() and host_cpuid() don't need to check
CONFIG_KVM, as they don't have any KVM-specific function calls.

Tested to build successfully with CONFIG_KVM disabled, using the
following CFLAGS combinations: "-DNDEBUG", "-DNDEBUG -O', "-DNDEBUG
-O0", "-DNDEBUG -O1", "-DNDEBUG -O2".
