URL: https://github.com/llvm/llvm-project/commit/8cdf6346f46c505928a9fb9d3ef9e8ce125a2108 DIFF: https://github.com/llvm/llvm-project/commit/8cdf6346f46c505928a9fb9d3ef9e8ce125a2108.diff LOG: [clang] Add test for CWG3129 (#206335) Adds a test for [CWG3129](https://wg21.link/CWG3129) "Clarify which floating-point-literals are valid". Clang has supported floating-point literals with overly tiny or huge exponents since 3.0, with only a warning emitted.
