[flang] Limits C++ implementation behaviors

The issue addressed here is the use of cast between object pointers
and function pointers. It is implementation defined because C++,
just like C, does not mandate that function and object pointers
must have the same size.
It is needed to have such cast because it is a will to ba able to
call inside F18 numerical function from libraries linked during
a Fortran program compilation in order to perform folding.
dlopen returns function pointers as void* that need to be cast to
pointer before use.
This change limits the usage of such cast inside ifdefs where POSIX
is required. In POSIX context, such cast is defined. Dlopen is
anyway used only if the environment is POSIX compliant.
In the rest of the code, opaque function pointers have been changed
from void* to void*(*)(). reinterpret_cast from function pointer to
function pointer are standard compliant.

[flang] Strip whitespace from parse tree source locations

Parse tree nodes have `source` fields that map the node back to
a range in the cooked input stream. These are used for names and
to locate error messages.

This change strips spaces from the beginning and end of those
source ranges before they are saved. This fixes two problems:
1. For a statement like this: `generic :: operator(+) => ...`,
   the name of the symbol we want to create is "operator(+)" but
   the parser was including the following space in the CharBlock
   it captured.
2. Error messages referring to parts of expressions sometimes included
   extra spaces in the source locations. For example:
   ```
   t.f90:9:29: error: subscripts may be applied only to an object or component
    integer, parameter :: b = a(1) + 1
                              ^^^^^
   t.f90:4:8: error: operands to LOGICAL operation must be LOGICAL
    i = j .or. k
         ^^^^^^^

Name resolution for defined operators

Original-commit: flang-compiler/f18@6b3edf2b713074c33ff2bfb6f748590d247b8cbc

[flang] Name resolution for defined operators

Instead of tracking just genericName_ while in a generic interface
block or generic statement, now we immediately create a symbol for it.
A parser::Name isn't good enough because a defined-operator or
defined-io-generic-spec doesn't have a name.

Change the parse tree to add a source field to GenericSpec. Use these
as names for symbols for defined-operator and defined-io-generic-spec
(e.g. "operator(+)" or "read(formatted)").

Change the source for defined-op-name to include the dots so that they
can be distinguished from normal symbols with the same name (e.g. you
can have both ".foo." and "foo"). These symbols have names in the symbol
table like ".foo.", not "operator(.foo.)", because references to them
have that form.

Add GenericKind enum to GenericDetails and GenericBindingDetails.
This allows us to know a symbol is "assignment(=)", for example,
without having to do a string comparison.

Add GenericSpecInfo to handle analyzing the various kinds of
generic-spec and generating symbol names and GenericKind for them.

Add reference to LanguageFeatureControl to SemanticsContext so that
they can be checked during semantics. For this change, if
LogicalAbbreviations is enabled, report an error if the user tries
to define an operator named ".T." or ".F.".

Add resolve-name-utils.cc to hold utility functions and classes that
don't have to be in the ResolveNamesVisitor class hierarchy. The goal
is to reduce the size of resolve-names.cc where possible.
