The operators FLOOR, CEILING, CMPLX, LBOUND, UBOUND, and SIZE accept (some only with Fortran 2003) the optional parameter KIND. This parameter determines the kind of the associated return value. So far, implementation of this kind parameter has been missing in GDB. Additionally, the one argument overload for the CMPLX intrinsic function was not yet available. This patch adds overloads for all above mentioned functions to the Fortran intrinsics handling in GDB. It re-writes the intrinsic function handling section to use the helper methods wrap_unop_intrinsic/wrap_binop_intrinsic/wrap_triop_intrinsic. These methods define the action taken when a Fortran intrinsic function is called with a certain amount of arguments (1/2/3). The helper methods fortran_wrap2_kind and fortran_wrap3_kind have been added as equivalents to the existing wrap and wrap2 methods. After adding more overloads to the intrinsics handling, some of the operation names were no longer accurate. E.g. UNOP_FORTRAN_CEILING has been renamed to FORTRAN_CEILING as it is no longer a purely unary intrinsic function. This patch also introduces intrinsic functions with one, two, or three arguments to the Fortran parser and the UNOP_OR_BINOP_OR_TERNOP_INTRINSIC token has been added.
