Peter Klausler c7f4c333af [flang] Make NEWUNIT= use a range suitable for INTEGER(KIND=1) and recycle unit numbers
Use a bit-set to manage runtime-generated I/O unit numbers, recycle
them after they're closed, and use a range of values that fits in
a minimal-sized integer.

Peter Klausler 702c0cfa07 [flang] runtime perf: larger I/O buffer growth increments
When reallocating an I/O buffer to accommodate a large record,
ensure that the amount of growth is at least as large as the
minimum initial record size (64KiB).  The previous policy was
causing input buffer reallocation for each byte after the minimum
buffer size when scanning input data for record termination
newlines.

Peter Klausler 52a1346b78 [flang] Distinguish intrinsic from non-intrinsic modules
For "USE, INTRINSIC", search only for intrinsic modules;
for "USE, NON_INTRINSIC", do not recognize intrinsic modules.
Allow modules of both kinds with the same name to be used in
the same source file (but not in the same scoping unit, a
constraint of the standard that is now enforced).

The symbol table's scope tree now has a single instance of
a scope with a new kind, IntrinsicModules, whose children are
the USE'd intrinsic modules (explicit or not).  This separate
"top-level" scope is a child of the single global scope and
it allows both intrinsic and non-intrinsic modules of the same
name to exist in the symbol table.  Intrinsic modules' scopes'
symbols now have the INTRINSIC attribute set.

The search path directories need to make a distinction between
regular directories and the one(s) that point(s) to intrinsic
modules.  I allow for multiple intrinsic module directories in
the second search path, although only one is needed today.

Peter Klausler f651bbea06 [flang] Correct interpretation of RECL=
When RECL= is set on OPEN(), ensure that it:
  1) enforces a max output record payload size
     (not including header+footer or newline), and
  2) causes padding of short output records only
     for ACCESS='DIRECT'

The previous code was causing some false overrun errors
and applying padding to sequential/stream output files.

[flang] Initial lowering for empty program
This patch enable lowering from Fortran to FIR for a basic empty
program. It brings all the infrastructure needed for that. As discussed
previously, this is the first patch for lowering and follow up patches
should be smaller.

With this patch we can lower the following code:

```
program basic
end program
```

To a the FIR equivalent:

```
func @_QQmain() {
  return
}
```

Follow up patch will add lowering of more complex constructs.

Jean Perier 416e503adf [flang] split character procedure arguments in target-rewrite pass
When passing a character procedure as a dummy procedure, the result
length must be passed along the function address. This is to cover
the cases where the dummy procedure is declared with assumed length
inside the scope that will call it (it will need the length to allocate
the result on the caller side).

To be compatible with other Fortran compiler, this length must be
appended after all other argument just like character objects
(fir.boxchar).

A fir.boxchar cannot be used to implement this feature because it
is meant to take an object address, not a function address.

Instead, argument like `tuple<function type, integer type> {fir.char_proc}`
will be recognized as being character dummy procedure in FIR. That way
lowering does not have to do the argument split.

This patch adds tools in Character.h to create this type and tuple
values as well as to recognize them and extract its tuple members.

It also updates the target rewrite pass to split these arguments like
fir.boxchar.

This part is part of fir-dev upstreaming. It was reviwed previously

are capable of dealing with repetition in their callees, so the bug
hadn't been exposed before.
