Our current codegen for MVE always calls out to helper functions,
because some byte lanes might be predicated. The common case is that
in fact there is no predication active and all lanes should be
updated together, so we can produce better code by detecting that and
using the TCG generic vector infrastructure.
Add a TB flag that is set when we can guarantee that there is no
active MVE predication, and a bool in the DisasContext. Subsequent
patches will use this flag to generate improved code for some
instructions.
In most cases when the predication state changes we simply end the TB
after that instruction. For the code called from vfp_access_check()
that handles lazy state preservation and creating a new FP context,
we can usually avoid having to try to end the TB because luckily the
new value of the flag following the register changes in those
sequences doesn't depend on any runtime decisions. We do have to end
the TB if the guest has enabled lazy FP state preservation but not
automatic state preservation, but this is an odd corner case that is
not going to be common in real-world code.

Architecturally, for an M-profile CPU with the LOB feature the
LTPSIZE field in FPDSCR is always constant 4. QEMU's implementation
enforces this everywhere, except that we don't check that it is true
in incoming migration data.
We're going to add come in gen_update_fp_context() which relies on
the "always 4" property. Since this is TCG-only, we don't actually
need to be robust to bogus incoming migration data, and the effect of
it being wrong would be wrong code generation rather than a QEMU
crash; but if it did ever happen somehow it would be very difficult
to track down the cause. Add a check so that we fail the inbound
migration if the FPDSCR.LTPSIZE value is incorrect.

Currently gen_jmp_tb() assumes that if it is called then the jump it
is handling is the only reason that we might be trying to end the TB,
so it will use goto_tb if it can. This is usually the case: mostly
"we did something that means we must end the TB" happens on a
non-branch instruction. However, there are cases where we decide
early in handling an instruction that we need to end the TB and
return to the main loop, and then the insn is a complex one that
involves gen_jmp_tb(). For instance, for M-profile FP instructions,
in gen_preserve_fp_state() which is called from vfp_access_check() we
want to force an exit to the main loop if lazy state preservation is
active and we are in icount mode.
Make gen_jmp_tb() look at the current value of is_jmp, and only use
goto_tb if the previous is_jmp was DISAS_NEXT or DISAS_TOO_MANY.

Sleep on WFI until the VTIMER is due but allow ourselves to be woken
up on IPI.
In this implementation IPI is blocked on the CPU thread at startup and
pselect() is used to atomically unblock the signal and begin sleeping.
The signal is sent unconditionally so there's no need to worry about
races between actually sleeping and the "we think we're sleeping"
state. It may lead to an extra wakeup but that's better than missing
it entirely.

Currently all of the M-profile specific code in arm_cpu_reset() is
inside a !defined(CONFIG_USER_ONLY) ifdef block. This is
unintentional: it happened because originally the only
M-profile-specific handling was the setup of the initial SP and PC
from the vector table, which is system-emulation only. But then we
added a lot of other M-profile setup to the same "if (ARM_FEATURE_M)"
code block without noticing that it was all inside a not-user-mode
ifdef. This has generally been harmless, but with the addition of
v8.1M low-overhead-loop support we ran into a problem: the reset of
FPSCR.LTPSIZE to 4 was only being done for system emulation mode, so
if a user-mode guest tried to execute the LE instruction it would
incorrectly take a UsageFault.
Adjust the ifdefs so only the really system-emulation specific parts
are covered. Because this means we now run some reset code that sets
up initial values in the FPCCR and similar FPU related registers,
explicitly set up the registers controlling FPU context handling in
user-emulation mode so that the FPU works by design and not by
chance.
