Don't use the fact that we stopped with a "Breakpoint" stop reason to decide to step over the breakpoint.  It's 
better to check directly whether there is a breakpoint site at the PC.

DoesBranch needs to compute the instruction if it isn't already done.

The step by running from branch to branch pretty much works with this checkin (at least for x86_64) but is still
turned off, it needs more qualification.  If you want to play with it, change the initialization of m_use_fast_step
to true.
