Flang transformational runtime was previously reporting conformity
issues in a zero based fashion to describe which dimension is non
conformant. This may confuse Fortran user, especially when the message
is about a dimension other than the first one.

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.

In 'STOP bye bye', do not print 'Fortran STOP:` before 'bye bye' when
NO_STOP_MESSAGE environment variable is set at runtime.
Also only exit with code 1 in StopStatementText if this is an ERROR STOP.
This matches other compiler behaviors.
Move STOP related unit tests in their own test file and add new tests to
cover this change.

The 'A' edit descriptor once served as a form of raw I/O of bytes
to/from variables that weren't of type CHARACTER (which itself
didn't exist until F'77). This usage was especially common for
output of numeric variables that had been initialized with Hollerith.

Support the extension intrinsic subroutines EXIT([status]) and ABORT()
in the intrinsic table and runtime support library. Lowering remains
to be done.

Move the closure of the subset of flang/runtime/*.h header files that
are referenced by source files outside flang/runtime (apart from unit tests)
into a new directory (flang/include/flang/Runtime) so that relative
include paths into ../runtime need not be used.
flang/runtime/pgmath.h.inc is moved to flang/include/flang/Evaluate;
it's not used by the runtime.

Port external-io test to use GTest. Remove Runtime tests directory.
Rename RuntimeGTest directory to Runtime.
This is the last in a series of patches which ported tests from the old
flang/unittests/Runtime test directory to use GTest in a temporary
unittest directory under flang/unittests/RuntimeGTest. Now that all the
tests in the old directory have been ported to use GTest, the old
directory has been removed and the GTest directory has been renamed to
flang/unittests/Runtime.
