<summary>Changes</summary>
Clang provides a number of headers which are required because the compiler is the only part of the implementation which can provide the correct macro definitions. Things like <limits.h> or <stdint.h> are such headers.
<tgmath.h> is not something the compiler needs to provide macros for; it is the responsibility of the C Standard Library to provide these interfaces.
Historically, Clang has provided tgmath.h from a time when C11 was still new and not all C Standard Libraries (such as the one from MSVC) had correct support. Today, that's no longer the case. So this change removes <tgmath.h> from the set of headers Clang provides and it is now on the user to provide a conforming C Standard Library if they would like to use this functionality.
