Commit Message

Micro-optimize PFR fields detection (#188)

* Start upper bound fields search from `4` fields, to avoid slow startup on typical workloads
* Inline the `fields_count_binary_search_unbounded` function to reduce template instantiations depth by 1
* Renamed `min` to `min_of_size_t` to avoid weired syntax
* Applied idea of better error reporting from #120
* Do not start fields count computation if one of the static asserts failed. That speedups error reporting in edge cases
* Use `std::*_t` versions of traits as they are faster in some implementations
* Rewrite binary search to simplify it and to avoid degradation to linear search on types that have constructor from variadic pack
* Remove default template parameters to simplify code

As a result, the whole test suite now runs 10%-25% faster on MSVC, ~20% faster on Clang, and 7%-20% faster on GCC.
