'std::experimental::parallelism_v2::simd_abi' as 'simd_abi'.
On x86, diagnose _VecBuiltin<16>, _VecBuiltin<32>, and

This hides the basic_string template in all diagnostics, reducing the
signal-to-noise ratio significantly. It also hides the std::__cxx11

The general idea of this change is to print template parms wherever they
would appear in the source code as well. Thus, the diagnostics code
needs to know whether any template parameter was given explicitly.

With the attribute, it is possible to solve PR89370 and make
std::__cxx11::basic_string<_CharT, _Traits, _Alloc> appear as
std::string in diagnostic output without extra hacks to recognize the
