Today this is what happens when we encounter hwcaps we cannot handle:
vex: priv/main_main.c:329 (LibVEX_Translate): Assertion
`are_valid_hwcaps(VexArchAMD64, vta->archinfo_host.hwcaps)' failed.
Running with -d offers this much enlightenment:
--7732:1:main ... arch = AMD64, hwcaps = INVALID
Not a good base for a bug report...
With this change, the user experience will be smoewhat better, e.g.:
VEX: Support for AVX2 requires AVX capabilities
Found: amd64-cx16-rdtscp-sse3-avx2
Cannot continue. Good-bye
Specifically, the patch decouples showing hwcaps and deciding their validity.
show_hwcaps_<ARCH> reports the hwcaps it finds. It never returns NULL.
check_hwcaps checks the hwcaps for feasibility and does not return in case
VEX cannot deal with them.
The function are_valid_hwcaps no longer exists.
