Add a configure-time check for QT_COMPILER_SUPPORTS_SIMD_ALWAYS
This has two main benefits:
1) introduces a qmake CONFIG we can use in .pro/.pri/.prf files
2) removes the need to keep an up-to-date list of which compilers
support the feature
The test is implemented as trying to compile every single SIMD test we
currently have, but without passing the -mXXX option. The reason for
trying all of them is that some people may have modified their mkspecs
to add -mXXX options or -march=XXX, which could enable the particular
feature we tried, resulting in a false positive outcome.
