This patch adds support for MCQ defined in UFSHCI 4.0. This patch
utilized the legacy I/O codes as much as possible to support MCQ.
MCQ operation & runtime register is placed at 0x1000 offset of UFSHCI
register statically with no spare space among four registers (48B):
UfsMcqSqReg, UfsMcqSqIntReg, UfsMcqCqReg, UfsMcqCqIntReg
The maxinum number of queue is 32 as per spec, and the default
MAC(Multiple Active Commands) are 32 in the device.
Example:
-device ufs,serial=foo,id=ufs0,mcq=true,mcq-maxq=8

FEAT_WFxT introduces new instructions WFIT and WFET, which are like
the existing WFI and WFE but allow the guest to pass a timeout value
in a register. The instructions will wait for an interrupt/event as
usual, but will also stop waiting when the value of CNTVCT_EL0 is
greater than or equal to the specified timeout value.
We implement WFIT by setting up a timer to expire at the right
point; when the timer expires it sets the EXITTB interrupt, which
will cause the CPU to leave the halted state. If we come out of
halt for some other reason, we unset the pending timer.
We implement WFET as a nop, which is architecturally permitted and
matches the way we currently make WFE a nop.

The TCGCPUOps::cpu_exec_halt method is called from cpu_handle_halt()
when the CPU is halted, so that a target CPU emulation can do
anything target-specific it needs to do. (At the moment we only use
this on i386.)
The current specification of the method doesn't allow the target
specific code to do something different if the CPU is about to come
out of the halt state, because cpu_handle_halt() only determines this
after the method has returned. (If the method called cpu_has_work()
itself this would introduce a potential race if an interrupt arrived
between the target's method implementation checking and
cpu_handle_halt() repeating the check.)
Change the definition of the method so that it returns a bool to
tell cpu_handle_halt() whether to stay in halt or not.
We will want this for the Arm target, where FEAT_WFxT wants to do
some work only for the case where the CPU is in halt but about to
leave it.

It also prevents enabling the strict mode of CFI which is currently
disabled with -fsanitize-cfi-icall-generalize-pointers.
The problematic casts are necessary to pass visit_type_T() and

LeakSanitizer complains about allocations whose references are held
only by automatic variables. It is possible to free them to suppress
the complaints, but it is a chore to make sure they are freed in all
exit paths so make them static instead.
