Sorry I just remember that we do have `_u128` literal for testing: https://github.com/llvm/llvm-project/blob/main/libc/test/src/__support/str_to_long_double_test.cpp#L24

Do you mind updating this test file to use it?  They will need to depend on `libc.src.__support.integer_literals` target.

Thanks,
