Richard Smith d8a2815903 [clang] implement current direction of CWG2765 for string literal comparisons in constant evaluation (#109208) ...

Track the identity of each string literal object produced by evaluation
with a global version number. Accept comparisons between literals of the
same version, and between literals of different versions that cannot
possibly be placed in overlapping storage. Treat the remaining
comparisons as non-constant.
