Track the locations of local variables using EF_debug annotations.
SimplLocals:
- record locations of stack-allocated variables with annotations
(of kind 5) at the beginning of the function;
- mark every assignment to non-stack-allocated variables with an
annotation of kind 2.
Debugvar: (new pass!)
- perform availability analysis for debug annotations of kind 2
- insert "start of live range" and "end of live range" annotations
(kind 3 and 4) to delimit intervals of PCs where the location
of a local variable is known.
