David Brownell <david-b@pacbell.net> Clean up ARM7/ARM9 EmbeddedICE register handling ... don't use parallel
arrays (error prone) or assume all registers are 32-bits wide (they can
have fewer bits); don't use spaces in register names, so they can be
passed more easily to the "reg" command.

Minor updates for ARM9 vector_catch support:  it's an 8-bit value.  This
seems to help this core's vector_catch command work a bit better; but its
behavior wih the register cache is still goofy.
