Add TM selftest to check if FP or VEC register values from one process
can leak into another process when both run on the same CPU.
This tests for CVE-2019-15030 and CVE-2019-15031.

This doesn't build on 64-bit big endian:
tm-poison.c: In function 'tm_poison_test':
tm-poison.c:118:10: error: format '%lx' expects argument of type 'long unsigned
int', but argument 2 has type 'uint64_t {aka long long unsigned int}'

printf("Unknown value %#lx leaked into f31!\n", unknown);

Sorry. I sent a v2 addressing it. Now I tested the fix against Travis CI.
Thank you.
Cheers,
