724cfce5 - [Clang] Do not assume a perfect match is a better match than a non-template non-perfect match (#149504)

[Clang] Do not assume a perfect match is a better match than a non-template non-perfect match (#149504) This fixes a regression introduced by the "perfect match" overload resolution mechanism introduced in 8c5a307. [This does regress the performance noticeably (-0.7% for a stage 2 build)](https://llvm-compile-time-tracker.com/compare.php?from=42d2ae1034b287eb60563c370dbf52c59b66db20&to=82303bbc3e003c937ded498ac9f94f49a3fc3d90&stat=instructions:u), however, the original patch had a +4% performance impact, so we are only losing some of the gain, and this has the benefit of being correct and more robust. Fixes #147374
