Improving the performance of breakpoints up to 50% (by playing with laziness)
This patch performs several optimizations with the goal of minimizing the cost of building the arguments to breakpointJump:
- Group them all in a single tuple, to minimize closure creation in heap
- Wrap this with the GHC.Base.lazy combinator, to induce max laziness
- Remove as many literal strings as possible
* injecting a module-local CAF to store the module name and use that
* eliminating the package string (not needed).
