Force removal of include/vgversion.h.tmp in make_or_upd_vgversion_h.
When someone created a read only src dir and builds in a separate build
dir then the original read only vgversion.h is copied from the src dir
into the build dir as vgversion.h.tmp (also read only). It could then
not be removed again in the auxprogs/make_or_upd_vgversion_h script.

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.

they caused the output to be inconsistent on Linux and Solaris.

mips: rewrite parts of mips_dirtyhelper_rdhwr
The idea behind this change is to be less dependent on build-flags, and
more dependent on runtime environment.
So, if the code is compiled for mips32r1, it should be able to execute
mips32r2 code if the platforms supports it.

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.
