This adds hints to the various "prfm" instructions so that they can
affect the instruction cache as well as the data cache.

    + 80 column violations.
    + Tab characters.
    + TableGen brace placement.

No functional changes.

19254c49a8 Remove cyclic dependency in AArch64 libraries

parts of the backend into a separate library. Previously they resided in
AArch64Desc, which created a circular dependency between various components.
