Create an FTLExceptionHandlerManager abstraction
https://bugs.webkit.org/show_bug.cgi?id=151079
Reviewed by Mark Lam.
Before, we used to manage the {stackmapRecordIndex => OSRExit} relationship
for exception handlers with a locally allocated HashMap and a few different
lambdas and random checks. It's cleaner and more manageable to just create
a class that handles this abstraction for us. This class provides nice helper
functions for everything we need. This abstraction makes reading the code easier.
And it will also makes hacking on the code in the future easier.
