Get rid of the copies of the opcode table pointers.

This inclduded fixing all the accessor functions to refer to the
global ones defined in InstrUtils.[ch] instead of taking separate
"table pointer" arguments.

This did end up adding a few more truly global references to some of
the code paths, particularly when performing dex optimization, so I
went ahead and measured the time to do a cold first-boot both before
and after the change (on real hardware). The times were identical (to
one-second granularity), so I'm reasonably comfortable making this
change.
