  Log Message:
  -----------
  [flang] Handle volatility in lowering and codegen (#135311)

* Enable lowering and conversion patterns to pass volatility information
from higher level operations to lower level ones.
* Enable codegen to pass volatility to LLVM dialect ops by setting an
attribute on loads, stores, and memory intrinsics.
* Add utilities for passing along the volatility from an input type to
an output type.

To introduce volatile types into the IR, entities with the volatile
attribute will be given a volatile type in the bridge; this is not
enabled in this patch. User code should not result in IR with volatile
types yet, so this patch contains no tests with Fortran source, only IR
that already contains volatile types.

Part 3 of #132486.
