Details

Implement the js::dbg2::Breakpoint class, including insertion and removal. This entails:

* turning the various sorts of breakpoint locations into JSScript,offset pairs
* searching JSScript lists to insert and remove traps
* managing multiple breakpoints set at the same bytecode
* inserting traps for existing breakpoints into newly loaded code (pending breakpoints)
* coping with scripts being garbage collected
* interlocking with JägerMonkey to insure that breakpoints are never set in functions that have JM frames on the stack
