The default KIND of some size/position intrinsic functions should not be default integer

[klausler]

Fortran mandates that the default kind of INTEGER occupy one numeric storage unit; so does the default kind of REAL. In 2019, default REAL is expected to be IEEE-754 single precision. Consequently, the default kind of INTEGER ends up having to be 32 bits wide.

This is a problem for real applications using arrays that are (or can be) very large, as the default KIND= parameter values for intrinsic functions like SIZE, SHAPE, LBOUND, UBOUND, FINDLOC, MAXLOC, and MINLOC (*) are all defined to be the default kind of INTEGER. One must determine the proper kind of "long" integer (or assume it) and remember to specify that KIND= on every use of these intrinsic functions in order to ensure that they work with large arrays.

I propose that the default result kinds of these intrinsic functions be redefined to be processor-dependent, so that a processor supporting large memories can do the obvious right thing.

(*) this list is probably incomplete; maybe it should include LEN but that's less of an issue and it would be the hardest to change
