ab9cfa0452 target/ppc: unify cpu->has_work based on cs->interrupt_request
Now that cs->interrupt_request indicates if there is any unmasked
interrupt, checking if the CPU has work to do can be simplified to a
single check that works for all CPU models.

2fdedcbc69 target/ppc: introduce ppc_maybe_interrupt
This new method will check if any pending interrupt was unmasked and
then call cpu_interrupt/cpu_reset_interrupt accordingly. Code that
raises/lowers or masks/unmasks interrupts should call this method to
keep CPU_INTERRUPT_HARD coherent with env->pending_interrupts.

Overall, these instructions are the hardest ones to measure performance
as the gvec implementation is affected by the immediate. Above there are
5 different scenarios when it comes to immediate and 2 when it comes to
rept/loop combination. The immediates scenarios are: all bits are 0
therefore the target register should just be changed to 0, with 1 bit
set, with 2 bits set in a combination the new implementation can deal
with using gvec, 4 bits set and the new implementation can't deal with
it using gvec and all bits set. The rept/loop scenarios are high loop
and low rept (so it should spend more time executing it than translating
it) and high rept low loop (so it should spend more time translating it
than executing this code).
These comparisons are between the upstream version, a previous similar
implementation and a one with a cleaner code(this one).
For a comparison with o previous different implementation:

da3c53bac3 target/ppc: Moved XSTSTDC[QDS]P to decodetree
Moved XSTSTDCSP, XSTSTDCDP and XSTSTDCQP to decodetree and moved some of
its decoding away from the helper as previously the DCMX, XB and BF were
calculated in the helper with the help of cpu_env, now that part was
moved to the decodetree with the rest.

As some values are now decoded outside the helper and passed to it as an
argument the number of arguments of the helper increased, the number
of TCGop needed to load the arguments increased. I suspect that's why
the slow-down in the tests with a high REPT but low LOOP.

a70a524710 target/ppc: Moved XVTSTDC[DS]P to decodetree
Moved XVTSTDCSP and XVTSTDCDP to decodetree an restructured the helper
to be simpler and do all decoding in the decodetree (so XB, XT and DCMX
are all calculated outside the helper).

Obs: The tests in this one are slightly different, these are the sum of
these instructions with all possible immediate and those instructions
are repeated 10 times.

This one to me seemed the opposite of the previous instructions, as it
looks like there was an improvement in the translation time (itself not
a surprise as operations were done twice before so there was the need to
translate twice as many TCGop)

slower translation but faster execution.

I wasn't expecting such a performance lost in both VPRTYBD and VPRTYBQ,
I'm not sure if it's worth to move those instructions. Comparing the
assembly of the helper with the TCGop they are pretty similar, so
I'm not sure why vprtybd took so much more time.

The significant difference in performance when REPT is low and LOOP is
high I think is due to the fact that the new implementation has a higher
translation time, as when using a helper only 5 TCGop are used but with
the patch a total of 10 TCGop are needed (Power lacks a direct mul_vec
equivalent so this instruction is implemented with the help of 5 others,
vmuleu, vmulou, vmrgh, vmrgl and vpkum).

db8fca024f tests/qtest: libqtest: Correct the timeout unit of blocking receive calls for win32
Some qtest cases don't get response from the QEMU executable under
test in time on Windows. It turns out that the socket receive call
got timeout before it receive the complete response.

The timeout value is supposed to be set to 50 seconds via the
setsockopt() call, but there is a difference among platforms.
The timeout unit of blocking receive calls is measured in
seconds on non-Windows platforms but milliseconds on Windows.
