If some node in tree is transformed changing the type, the outer node could potentially also change type. This patch implements a RetypingTreeMap that propagates those changes until types converge. Propagation is done for tree nodes that are able to compute their type based on their children: Pair, Block, If, Match, CaseDef, Try, SeqLiteral, Annotated, Select.
Test for order of type parameters in recursive call
TailRec now relies on FullParameterization and uses two passes for transformation. First one decides weather the method will be transformed and if yes, starts rewriting calls in taill position. Second one lifts the method body to a fully parameterized one, correcting types.
Hurray!
Used in FullParameterization to substitute type parameters. Fixes test failure for t2399.scala
