This allows using a function body as a source for a transform without
necessarily requiring a recompilation as well.

Chris Fallin de5c990d18 Avoid empty_blocks pass for now; seems problematic. 2023-02-21 22:48:19 -08:00
Chris Fallin 79b4e710c8 Avoid recursion in stackify. 
This commit rewrites `stackify` (Ramsey control-flow algorithm) with
explicit-stack control flow, using a state-machine stack, rather than
direct recursion. This avoids stack overflow for large function bodies.
