target-sh4: rename helper flags

Rename helper flags to the new ones. This is purely a mechanical change,
it's possible to use better flags by looking at the helpers.

target-sh4: implement addv and subv using TCG

addv and subv helpers implementation is directly copied from the SH4
manual and looks quite complex. It is however possible to explain it
without branches, and is therefore possible to implement it with TCG.

target-sh4: rework exceptions handling

Since commit fd4bab102 PC is restored in case of exception through code
retranslation. While it is clearly the thing to do in case it is not
not known if an helper is going to trigger an exception or not
(e.g. for load/store, FPU, etc.), it just make things slower when the...

target-sh4: implement addc and subc using TCG

Now that setcond is available, the addc and subc can easily be
implemented using TCG.

target-sh4: switch to AREG0 free mode

Add an explicit CPUState parameter instead of relying on AREG0
and switch to AREG0 free mode.

target-sh4: get rid of CPU_{Float,Double}U

SH4 is always using softfloat, so it's possible to have helpers directly
taking float32 or float64 value. This allow to get rid of conversions
through CPU_{Float,Double}U.

Using setcond it's now possible to generate a relatively short negc
instruction in TCG.

SH4: Implement FD bit

SH4 manual say that if a floating point instruction is executed while
FD bit in the status register is 1, an exception should be raised. QEMU
presently does not do that, so the kernel does not initialize FP state
for any thread, nor does it save/restore FP state. The most apparent...

fix a bug on 'sleep' instruction, which have caused halt of idle task.
As i386 'hlt' instruction does, it should save PC before sleep.
