* Add POWER8 VSX toolchains
POWER8, though slower than POWER9, is still used in the wild; these
toolchains should still be much faster on POWER8 than POWER8 without VSX
optimizations.
* VSX toolchains: set -cpu arg in QEMU CI tests
Improves compatibility with Clang 11.
Also rename NCNN_SSE* options to NCNN_VSX_SSE* to avoid conflict between
x86 and POWER (went unnoticed before because x86 doesn't have an option
for toggling SSE 4.1).

* Support Ingenic X2000 & T40
T40 claimed to have MIPS32R2 with MSA, but tested not working on my unit, so set to mips32r2 without MSA.
* Add Ingenic T40XP benchmark result
