feat(library/init/lean/compiler/ir): add unreachbranches.lean
...
New optimization pass for eliminating unreachable branches that occur
very often when using `ExceptT` and `EState`.
The current commit implements an abstract interpreter for computing
an approximation of the kinds of values returned by a function.
TODO:
- Implement `FnBody.jmp`.
- Implement `interpDecl`
- Remove unreachable branches in `FnBody.case`

feat(library/init/lean/compiler/ir): add persistent field to inc/dec
...
If `persistent == true`, then object is known to be persistent at
compilation time. `emitc` omits `inc/dec` operations to
persistent objects. The interpreter does not to avoid memory leaks.

refactor(library/init/lean/compiler/ir): remove redundant field from FnBody.jdecl
...
The result type of a join point is always equal to the function return
type. Moreover, the extra bookkeeping introduces extra work, and doesn't
really help.
