[PATCH] PR modula2/115112 Incorrect line debugging information occurs during INC builtin

This patch fixes location bugs in BuildDecProcedure,
BuildIncProcedure, BuildInclProcedure, BuildExclProcedure and
BuildThrow.  All these procedure functions use the token position
passed as a parameter (rather than from the quad stack).  It also
fixes location bugs in CheckRangeIncDec to ensure that the token
position is stored on the quad stack before calling subsidiary
procedure functions.
