ce7b6709 - [clang][OpenMP] Simplify check for repeated clauses (#93611)

[clang][OpenMP] Simplify check for repeated clauses (#93611) The `FirstClauses` is a vector of pointer-bool pairs, and the pointer part of the pair is never used. Replace the vector with std::bitset, and rename it to `SeenClauses` to make the purpose of it a bit clearer.
