expressions, now that Abramo has added proper type-source information
to those expressions.

extra checks for Darwin.

This change also fixes the use of FP to access frame indices in leaf
functions and cleaned up some confusing code in epilogue emission.

Make breakpoint commands work again.  Added a PerformAction to the stop info - actions are run when the
stop event is pulled from the event queue.  Then made the StopInfoBreakpoint's PerformAction do the 
breakpoint command.
Also fixed the StopInfoBreakpoint's GetDescription so it gets the breakpoint location info, not the breakpoint
site info.

register at a time. This turns out to be slightly faster than iterating over
instructions, but more importantly, it allows us to compute spill weights for
new registers created after the spill weight pass has run.

Also compute the allocation hint at the same time as the spill weight. This
allows us to use the spill weight as a cost metric for copies, and choose the
most profitable hint if there is more than one possibility.

The new hints provide a very small (< 0.1%) but universal code size improvement.
