David Brownell <david-b@pacbell.net> ARM disassembly support for about five dozen non-Thumb instructions
that were added after ARMv5TE was defined:

 - ARMv5J "BXJ" (for Java/Jazelle)
 - ARMv6 "media" instructions (for OMAP2420, i.MX31, etc)

Compile-tested.  This might not set up the simulator right for the
ARMv6 single step support; only BXJ branches though, and docs to
support Jazelle branching are non-public (still, sigh).

ARMv6 instructions known to be mis-handled by this disassembler
include:  UMAAL, LDREX, STREX, CPS, SETEND, RFE, SRS, MCRR2, MRRC2
