3f060bbc - [libc][math][NFC] Fix GCC diagnostics in math tests (#241530)

[libc][math][NFC] Fix GCC diagnostics in math tests (#241530) Building the math test suite with GCC surfaces conversion, narrowing, uninitialised-variable, and non-exhaustive return warnings, along with -Wattributes visibility warnings under -fvisibility-inlines-hidden when passing LIBC_ALWAYS_INLINE static_rounding functions as template arguments. Initialise tracking locals across range and shared tests, suffix float and float16 test literals with exact f and f16 hexadecimal forms, cast FModTest inputs with fputil::cast<T>, and wrap static_rounding helpers in static functions for exhaustive expf and exp2f tests. Guard the 64-bit long exponent checks in LdExpTest with if constexpr and mark the MPCUtils RoundingMode switch unreachable after covering all enumerators. Assisted-by: Automated tooling, human reviewed. --------- Co-authored-by: Tue Ly <lntue.h@gmail.com>
