llvm#168885) Add two more AST nodes, one for a misplaced end-directive, and one for an invalid string following the OpenMP sentinel (e.g. "!$OMP XYZ"). Emit error messages when either node is encountered in semantic analysis.
…ant fold (llvm#169217) Extension to llvm#168726 - ensure we peek through bitcasts to look for constants (as constant folding will) DAG should have constant folded this, but we're still fighting the lack of proper topological sorting. Fixes llvm#169205
Fold any-of (fcmp uno %A, %A), (fcmp uno %B, %B), ... -> any-of (fcmp uno %A, %B), ... This pattern is generated to check if any vector lane is NaN, and combining multiple compares is beneficial on architectures that have dedicated instructions.

Make it easier to use these containers as drop-in replacements for std::map.
… and flangFrontend (llvm#165277) This removes the dependency on clangDriver from clangFrontend and flangFrontend. This refactoring is part of a broader effort to support driver-managed builds for compilations using C++ named modules and/or Clang modules. It is required for linking the dependency scanning tooling against the driver without introducing cyclic dependencies, which would otherwise cause build failures when dynamic linking is enabled. In particular, clangFrontend must no longer depend on clangDriver for this to be possible. This change was discussed in the following RFC: https://discourse.llvm.org/t/rfc-new-clangoptions-library-remove-dependency-on-clangdriver-from-clangfrontend-and-flangfrontend/88773
