[mlir] [VectorOps] Add masked load/store operations to Vector dialect

[aartbik]

Summary

The intrinsics were already supported and vector.transfer_read/write lowered
direclty into these operations. By providing them as individual ops, however,
clients can used them directly, and it opens up progressively lowering transfer
operations at higher levels (rather than direct lowering to LLVM IR as done now).

Does a GEP without indices actually do something?

Thanks!

It is a nop. It seemed a bit cleaner to make all memoperations use a GEPOp, but perhaps I should remove it for the non-index cases (and use the base directly). This part is subject to change anyway, since I plan to general this for the cases not handled above, and move this into core utilities perhaps.

 .. option:: -q, --quiet
 
  Suppress any output except for test failures.
 
 .. option:: -s, --succinct
 
  Show less output, for example don't show information on tests that pass.
+ Also show a progress bar, unless ``--no-progress-bar`` is specificed.
 
 .. option:: -v, --verbose
 
  Show more information on test failures, for example the entire test output
  instead of just the test result.
 
 .. option:: -vv, --echo-all-commands
