This introduces the macro TOOLCHAIN_HAS_C_AUTO_TYPE to
indicate that the toolchain supports __auto_type. This is
supported since GCC 4.9.0 and Clang 3.8.0.

This introduces the macro TOOLCHAIN_HAS_PRAGMA_DIAG to indicate
that the toolchain supports #pragma diagnostics. This is

attribute is supported since Clang 10.
