Iain Ireland 70ddc40735 Bug 1630090: Implement PrepareAndExecuteRegexp for new engine r=jandem
The code in this patch lines up fairly closely with the old version of PrepareAndExecuteRegexp, but not so closely that I wanted to unify them, particularly since the old version will be going away. Aside from the changes to the layout of the input data, the main difference is that the return value is now being passed in a register instead of on the stack.
