QtBase: use new QStaticByteArrayMatcher where applicable
Even for compilers that don't yet support C++14 constexpr,
this should improve performance of searches a lot, if,
indeed, Boyer-Moore still is an optimization over linear
searching at all in these days of hardware prefetchers
and deep CPU pipelines, because the setup cost is only
incurred once. As function-statics, we also don't care
about startup ordering and cost.
It's a pity that the platform that would benefit the most
- Windows - doesn't have constexpr support, yet.
