[flang] Clean up includes

indirection.h: Doesn't need ../common because it is in common.

expression.h: ../lib is the wrong path but the includes are needed.
They were probably coming in indirectly through other includes.

token-parsers.h: Include was not needed and parser shouldn't have
dependency on evaluate.

Fix source locations for some expressions

Original-commit: flang-compiler/f18@ac4fb9a1bece3f01f3308fb2e7afc6e083f20d73
Reviewed-on: https://github.com/flang-compiler/f18/pull/395

[flang] Fix source locations for some expressions

When expressions are parsed iteratively they weren't getting the correct
source positions. For example, when parsing an `add-operand` as a sequence
of `mult-operand`s separated by `mult-op`.

This shows up when we report an error message referring to this kind
of expression:
```
t.f90:1:11: error: Expected a LOGICAL expression
  if (i * j * k) then
            ^^^
```

The fix is to remember the location of the first operand and then
for each sub-expression (`i * j` and `i * j * k` in this example)
extend its location back to include that first operand.

[flang] Check semantic contraints for the nullify statement. The full
legality check is up to the user; however, some checks could
be done at compile time and others at runtime.  We choose to
skip any checking at compile time because it would not be
complete.

Note the instantiation of ExtractDataRef in expressions.cc.
This instantiation satifies the reference in check-nullify.cc
because expression.h just has a declaration of ExtractDataRef
instead of the definition.

[flang] Support coarrays in name resolution

A coarray is represented as a `Symbol` with `ObjectEntityDetails` that
has a non-empty coshape. The coshape is represented using the same type
(`ArrayShape`) as the shape is, so the fact that it is a coshape is
determined from context.

Move code for analyzing shapes to `resolve-names-utils.cc` and
generalize it for coshapes.

In `symbol.cc` add dumping of coshapes. Simplify some of the functions
by adding some `Dump*` functions to handle common cases.

In `mod-file.cc` generalize the code for writing shapes to also write
coshapes. Fix a bug in `PutShapeSpec()`.

[flang] Rework .mod file writing for subprogram interfaces

A subprogram interface in a `.mod` file requires all of the symbols
needed to declare the function return value and dummy arguments.
Some of those were missing.

`SubprogramSymbolCollector` recursively discovers all such symbols,
including symbols used in type parameters, array bounds, character
lengths, parent types.

Common blocks require special handling: If any of the symbols that
are need appear in a common block, we have to include that common block
and all other symbols in it. To make that easier to figure out, add the
`commonBlock` property to `ObjectEntityDetails` to map the entity to
the common block it is in, if any.

[flang] Don't add inherited procedures to generic binding

In this example:
```
  type t1
  contains
    procedure, nopass :: s1
    generic :: foo => s1
  end type
  type, extends(t1) :: t2
  contains
    procedure, nopass :: s2
    generic :: foo => s2
  end type
```

The GenericBindingDetails for foo in t2 include both s1 and s2 as
specific procs. There is no way to distinguish between the binding in
the current type and the binding that was inherited. In particular,
the .mod file will have a binding for s1 in t2, so it won't match the
original source (for exampke, see the old version of modfile14.f90).
