When a thread hints that it is in a spin-wait loop (eg, x86 REP NOP insn),
deschedule the thread much sooner (300 evchecks) than previously (1000
evchecks). Once the thread is spinning, there's absolutely no point in
continuing with it, since only a different thread can get it out of the loop,
so we need to drop the current thread ASAP.

Compile fb_test_amd64 only if adx instructions can be compiled
Note: this just unbreaks the build on avx + non_adx capable systems
(such as gcc farm gcc20).
adx capable system should probably be better handled:
* ./tests/x86_amd64_features cannot check for adx flag
(so fb_test_amd64 is run if compiled and system is avx capable, which
might give problems if gcc/as can compile the test, but the cpu
cannot execute adx instructions)
* on an adx capable system, a native run of cpuid tells it is adx capable
but under valgrind, cpuid reports the valgrind synthetic cpu is not adx
capable.

Add a test for amd64 basic instructions, with particular emphasis on testing
condition codes. This is originally by Fabrice Bellard (GPL2+'d), with MD5
support from Alexander Peslyak (public domain) and has been extended to cover
ADOX and ADCX as per bug #360415.
The program generates more than 800MB of output, which it MD5 sums, so the final
MD5 sum serves as the pass/fail check. It takes roughly a minute to run.
Fix mempool2 test
mempool2 test was using a wrong address for the pool arguments
in the client requests VALGRIND_MEMPOOL_FREE.
So, instead of testing what it was supposed to test (e.g. reading
memory from a freed mempool block), this was all causing
an illegal memory pool address.
So, fix the calls, and add a specific test to verify the illegal
mempool address.

PPC64 ISA 3.0B, add support for the additional instructions: addex, mffscdrn,
mffscdrni, mffsce, mffscrn, mffscrni, mffsl. vmsumudm.
Additionally, the OV32 and CA32 bits were introduced in ISA 3.0 but
Valgrind add support for setting these bits for ISA 3.0. The OV32 and CA32
bits must now be set on a number of pre ISA 3.0 instructions. So now the
instructions produce different results in the XER register. Thus we need pre
and post ISA 3.0 expect files. Command line options were added to thee
pre ISA test cases so instructions that didn't change could be run with one
set of command line args. The instructions that have different XER results
are run using a different set of command line args. The tests were split into
two, one for instructions that didn't change on for instructions that do
change under ISA 3.0. We then create ISA3.0 expect files only for the tests
that run differently. By doing this we minimized the size of the expect files
needed.
Vex commit 3359 Has the source code changes for the instruction and OV32, CS32

This commit is all the test case changes, adding the new test case files.
