  -----------
  [LangRef] Add memory attribute

This adds the LangRef wording for the memory attribute proposed at
https://discourse.llvm.org/t/rfc-unify-memory-effect-attributes/65579.

The old attributes are not removed from LangRef until the migration
is finished.

  Log Message:
  -----------
  [IR] Add support for memory attribute

This implements IR and bitcode support for the memory attribute,
as specified in https://reviews.llvm.org/D135597.

The new attribute is not used for anything yet (and as such, the
old memory attributes are unaffected).
