Mark de Wever 99d5fad7a5 [libc++] Remove invalid C++20 code from a test. 
During the review of D91986 it has been discovered the in C++11
deprecated `throw()` exception specification has been removed in
C++20. Removed the part of the test code using this feature.

Louis Dionne 31cbe0f240 [libc++] Remove the c++98 Lit feature from the test suite 
C++98 and C++03 are effectively aliases as far as Clang is concerned.
As such, allowing both std=c++98 and std=c++03 as Lit parameters is
just slightly confusing, but provides no value. It's similar to allowing
both std=c++17 and std=c++1z, which we don't do.

This was discovered because we had an internal bot that ran the test
suite under both c++98 AND c++03 -- one of which is redundant.

Eric Fiselier 601f763182 [libcxx] Adds [concept.same] 
Patch from Christopher Di Bella (cjdb@google.com)
Reviewed as https://reviews.llvm.org/D74291

Adds `std::same_as` to libc++. Since there aren't clang-format rules for
//requires-expressions//, I'll need to disable the formatter in certain areas.
