This commit makes preparatory changes to the GCC diagnostics interface to enable support for #pragma GCC diagnostic within the LTO streaming code. It involves making a type name public, adding a range indicator to an enum for LTO’s convenience, and removing unused, potentially incorrect logic from a diagnostic classification function. These adjustments facilitate LTO’s ability to manage diagnostic settings across compilation units.
