[flang] Name resolution for Cray pointers

Resolve the pointer and pointee names in a `BasedPointerStmt` and
enforce some of the constraints on them. There are still some
constraints to be implemented, mainly about what kind of attributes
the pointers and pointees can have.

The rules for these are a little vague. I mostly followed
- Cray Fortran Reference Manual section 9.3.2
- https://gcc.gnu.org/onlinedocs/gfortran/Cray-pointers.html
- VSI Fortran for OpenVMS Language Reference Manual section B.11

Note that the first two use the term "Cray pointer" but the last does
not. That is confusing because you have to know from context whether
it is referring to Cray pointers or Fortran pointers, so I used
"Cray pointer" and "Cray pointee" in error messages to refer to the
two names in the pointer statement.

[flang] Fix bug with statement functions

When the name of a statement function was previously declared, we
weren't correctly recognizing it as a statement function. E.g.
```
integer :: f, i
f(i) = i + 1
```

`f` was entered in the symbol table with `EntityDetails` and the
`parser::Name` on the first line was resolved to that symbol.
On the second line we replaced the symbol for `f` in the scope
with a subprogram symbol, but that didn't change the symbol in
the first `parser::Name`.

The fix requires:
1. don't erase the original symbol for `f`, just replace its details
2. when we erase the symbol for `f` in the subprogram scope, don't
   unresolve it

[flang] Fix issue: Enforce specific intrinsic characteristics
Fix issue flang-compiler/f18#661.
The issue was that when probing a specific intrinsic, the
constraints of the related generic intrinsic were tested instead
of the more restrictive constraints of the specific intrinsic.

[flang] Fix SELECTED_CHAR_KIND('DEFAULT') folding issue
Fix issue flang-compiler/f18#676
The issue was that the 'DEFAULT' case was handled
directly in fold.cc which did not lowercase/trim trailing
space of the argument befaore comparing to "default".

Modify the `Selected_char_kind` function to accept the default
char kind as argument and to return it if the processed argument
matches "default".
