Diagnose OPEN(FILE=f) when f is already connected by the same name to
a distinct external I/O unit.

Add a header-only implementation of Briggs & Torczon's fast small
integer set data structure to flang/include/flang/Common, and use
it in the runtime to manage a pool of Fortran unit numbers with
recycling. This replaces the bit set previously used for that
purpose. The set is initialized on demand with the negations of
all the NEWUNIT= unit numbers that can be returned to any kind
of integer variable.
For programs that require more concurrently open NEWUNIT= unit
numbers than the pool can hold, they are now allocated with a
non-recycling counter. This allows as many open units as the
operating system provides.
Many of the top-line comments in flang/unittests/Runtime had the
wrong path name. I noticed this while adding a unit test for the
fast integer set data structure, and cleaned them up.

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.

When closing all open units, don't hold the unit map lock
over the actual close operations; if one of those aborts,
CloseAll() may be called and then deadlock.

Non-advancing I/O was failing; ExternalFileUnit was losing
track of what writes had been committed to the file. Fixed.
Also, support the common extension of $ and \ in a FORMAT
as being equivalent to ADVANCE=NO.

With derived type description tables now available to the
runtime library, it is possible to implement the concept
of "child" I/O statements in the runtime and use them to
convert instances of derived type I/O data transfers into
calls to user-defined subroutines when they have been specified
for a type. (See Fortran 2018, subclauses 12.6.4.8 & 13.7.6).
- Support formatted, list-directed, and NAMELIST
transfers to internal parent units; support these, and unformatted
transfers, for external parent units.
- Support nested child defined derived type I/O.
- Parse DT'foo'(v-list) FORMAT data edit descriptors and passes
their strings &/or v-list values as arguments to the defined
formatted I/O routines.
- Fix problems with this feature encountered in semantics and
FORMAT valiation during development and end-to-end testing.
- Convert typeInfo::SpecialBinding from a struct to a class
after adding a member function.

Rework initial implementation of external I/O unit operations to
fix problems exposed in unit tests (in a later patch). Add flushing.

New<A> used to return an A&; now it returns an OwningPtr<A>
to force better ownership tracking of allocations. Its API
has also been split into New<A> and SizedNew<A> to allow
allocations with a size override.
