5c62bfb4f8 [flang] Implement int_ptr_kind. 
Split omp_lib.F90 into two files: a Fortran file used to
create the omp_lib module and a .h file that can be used
directly, which apparently some codes do. Because of the
split, and wanting to avoid forcing use isc_c_binding,
use int_ptr_kind()  instead of c_intptr_t.

51fe223916 [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

8c4d2e8763 [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".

1. Big chunk: update comments in parse-tree.h and openmp-grammar.h

2. Update `To`, `Link`, and `From` clauses with `OmpObjectList` to allow
   `/Common Block/`. Spec does not mention whether `Common Block name`
   should be accepted or not, so we should assume that these clauses
   accept normal `list-item`, which is `Variable`, `Array Section`, or
   `Common Block name`.
