instructions use different values (e.g., 2-byte or 4-byte alignment).
Also fix ARMInstPrinter to print these alignments as bits instead of bytes.

TII::isMoveInstr is removed.

This fixes a "usr_junk" verification failure when installing into /usr.

independent of the order that isel happens to visit the dbg_declare
intrinsics. This fixes a bug in which the formal arguments were
being printed in reverse order, now that fast isel is going bottom up.

DIRS list, so it does no good to filter it from PARALLEL_DIRS), and replace
it with a check to disable building the shared library version of edis when
the flag is set.  Disabling it entirely does not work because MC uses it now.

"bonus" instruction to be speculatively executed.  Add a heuristic to
ensure we're not tripping up out-of-order execution by checking that this bonus
instruction only uses values that were already guaranteed to be available.

This allows us to eliminate the short circuit in (x&1)&&(x&2).
