Break Arrays

An array of words, indexed by a breakpoint number (breakpointId in Tickish) containing the ignore count for every breakpopint. There is one of these arrays per module.

For each word with value n: n > 1 : the corresponding breakpoint is enabled. Next time the bp is hit, GHCi will decrement the ignore count and continue processing. n == 0 : The breakpoint is enabled, GHCi will stop next time it hits this breakpoint. n == -1: This breakpoint is disabled. n < -1 : Not used.
