Michael Starzinger 02fee655b3 [interpreter] Avoid redundant {PopContext} instructions. 
This avoids emitting redundant {PopContext} bytecode instructions when
non-local control-flow leaves the method body. It also folds multiple
such {PopContext} instructions into one, in case several scoping levels
are crossed at one. Only the expected context of the target of a local
control-flow transfer matters.
