Enhancement of argument list parsing loop: removing break / continue operators, so that every iteration passes start and end of loop body.

Browse Source 
The change makes possible simple notification of byte-code generator about start / end of byte-code generation for an argument.
As register values are not passed between byte-code sequences that prepare different arguments, the change would make possible for byte-code generator to reuse registers allocated for the code sequences.
