Daniel Beer e9b6a77414 dis/sim: fix handling of opcodes with two indexed operands. 
If the source operand is indexed, and the destination is symbolic (PC +
index), then the base for the destination index is the program counter
*after* having fetched the source index.

Also, the addition of the index is done modulo 2^16 if the base points
within the lower 64 kB of memory.

Daniel Beer 18cf2a561f Separate and clean up break handling. 
Ctrl+C handling is done in ctrlc.c, and a break condition now persists
until the interactive reader begins to process the next command. The
condition is cleared by calling ctrlc_clear().
