OpenACC Specific Changes
------------------------
+- OpenACC support, enabled via `-fopenacc` has reached a level of completeness
+ to finally be at least notionally usable. Currently, the OpenACC 3.4
+ specification has been completely implemented for Sema and AST creation, so
+ nodes will show up in the AST after having been properly checked. Lowering is
+ currently a work in progress, with compute, loop, and combined constructs
+ partially implemented, plus a handful of data and executable constructs
+ implemented. Lowering will only work in Clang-IR mode (so only with a compiler
+ built with Clang-IR enabled, and with `-fclangir` used on the command line).
+ However, note that the Clang-IR implementation status is also quite partial,
+ so frequent 'not yet implemented' diagnostics should be expected. Also, the
+ ACC MLIR dialect does not currently implement any lowering to LLVM-IR, so no
+ code generation is possible for OpenACC.

I hope I can get the other two entries also to their right places, but thats not your job. |
Was easy enough to do while I was there, reviews here: #154608 Feel free to add folks you think are good at reviewing these. |

It was brought up in response to llvm#154605 that these two were in the wrong place as well! This patch tries to find better places for them, and moves them.
