    A transformation local to the body of the IMethod received as argument.

    A transformation local to the body of the IMethod received as argument. An linining decision consists in replacing a callsite with the body of the callee. Please notice that, because `analyzeMethod()` itself may modify a method body, the particular callee bodies that end up being inlined depend on the particular order in which methods are visited (no topological sorting over the call-graph is attempted).

    Making an inlining decision requires type-flow information for both caller and callee. Regarding the caller, such information is needed only for basic blocks containing inlining candidates (and their transitive predecessors). This observation leads to using a custom type-flow analysis (MTFAGrowable) that can be re-inited, i.e. that reuses lattice elements (type-flow information computed in a previous iteration) as starting point for faster convergence in a new iteration.

    The mechanics of inlining are iterative for a given invocation of `analyzeMethod(m)`, and are affected by inlinings from previous iterations (ie, "heuristic" rules are based on statistics tracked for that purpose):

    (1) before the iterations proper start, so-called preinlining is performed. Those callsites whose (receiver, concreteMethod) are both known statically can be analyzed for inlining before computing a type-flow. Details in `preInline()`

    (2) the first iteration computes type-flow information for basic blocks containing inlining candidates (and their transitive predecessors), so called `relevantBBs` basic blocks. The ensuing analysis of each candidate (performed by `analyzeInc()`) may result in a CFG isomorphic to that of the callee being inserted in place of the callsite (i.e. a CALL_METHOD instruction is replaced with a single-entry single-exit CFG, a substitution we call "successful inlining").

    (3) following iterations have `relevantBBs` updated to focus on the inlined basic blocks and their successors only. Details in `MTFAGrowable.reinit()`
