Adds support for ARM softfp calling convention.
...
The cross-compiler with the Android NDK doesn't support
the 'hard' calling convention, so we need both. I've
added a preprocessor define to the gyp file for the
standalone vm indicating support for 'hard' so that I
don't have to modify the Dartium gyp files.

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.

Adds mrc instruction to arm simulator, assembler, disassembler.
...
This instruction will be used to query an arm processor to
determine whether it supports the sdiv and udiv instructions.
Also adds a flag --sim_has_int_div to the arm simulator,
which changes the result of the mrc instruction so we can
test both ways.
