Drops into Simulator Debugger only in a session that is already interactive.
...
This change backs out an earlier change to the disassemblers that
made them return false if an instruction couldn't be decoded.
This was used in the simulator debuggers for arm and mips to avoid
executing an instruction that couldn't be decoded.
Instead, now when an unknown instruction is encountered in the simulator,
if the simulator is running interactively, we drop into
the debugger, and otherwise die. We detect that a simulator is
running interactively by setting a flag if we enter the debugger
for a user set break point.

82367b380d
Copies Simulator Debugger from ARM to MIPS.
...
Also includes changes to keep it from aborting unexpectedly.
Among other things, I changed the Disassembler::Disassemble to return false
when the underlying decoder can't decode an instruction. Then,
the MIPS SimulatorDebugger will refuse to step or cont on an instruction
that the Disassembler can't decode.
