Generate the array reallocation on assignment code before entering the
scalarization loops. This doesn't move the generated code itself,
which was already put before the outermost loop, but only changes the
current scope at the time the code is generated. This is a prerequisite
for a followup patch that makes the reallocation code create new
variables. Without this change the new variables would be declared in
the innermost loop body and couldn't be used outside of it.

* trans-expr.cc (gfc_trans_assignment_1): Generate array
reallocation code before entering the scalarisation loops.

It turned out that other compilers permit (require?) named constants
to appear in clauses - and programs actually use this. OpenACC 3.4
added therefore the following:
In this spec, a _var_ (in italics) is one of the following:
...
* a named constant in Fortran.
plus
If during an optimization phase _var_ is removed by the compiler,
appearances of var in data clauses are ignored.
Thus, all errors related to PARAMETER are now downgraded, most
to a -Wsurprising warning, but for 'acc declare device_resident'
(which kind of makes sense), no warning is printed.
In trans-openmp.cc, those are ignored, unless I missed some code
path. (If so, I hope the middle end removes them; but before
removing them for the covered cases, the program just compiled &
linked fine.)
Note that 'ignore PARAMETER inside clauses' in trans-openmp.cc
would in principle also apply to expressions ('if (var)') but
those should be evaluated during 'resolve.cc' + 'openmp.cc' to
their (numeric, logical, string) value such that there should
be no issue.

Finalize_component freeed an expression that it used to remember which

Add the preliminary code produced for the evaluation of the FROM and TO
arguments of the MOVE_ALLOC intrinsic before using their values.
Before this change, the preliminary code was ignored and dropped,
limiting the validity of the implementation of MOVE_ALLOC to simple
cases without preliminary code.
This change also adds the cleanup code of the same arguments. It
doesn't make any difference on the testcase though. Because of the
limited set of arguments that are allowed (variables or components
without subreference), it is possible that the cleanup code is actually
guaranteed to be empty. At least adding the cleanup code makes the
array case consistent with the scalar case.

While C/++ support the routines acc_attach{,_async} and
acc_detach{,_finalize}{,_async} routines since a long time, the Fortran
API routines where only added in OpenACC 3.3.
Unfortunately, they cannot directly be implemented in the library as

causes the attempted attachment to the this temporary variable instead
of to the original one.
Therefore, those API routines are handled in a special way in the compiler.

The temporary variables that are generated to implement SELECT TYPE
and TYPE IS statements have (before this change) a name depending only
on the type. This can produce confusing dumps with code having multiple
SELECT TYPE statements, as it isn't obvious which SELECT TYPE construct
the variable relates to. This is especially the case with nested SELECT
TYPE statements and with SELECT TYPE variables having identical types
(and thus identical names).
This change adds one additional user-provided discriminating string in
the variable names, using the value from the SELECT TYPE variable name
or last component reference name. The additional string may be
truncated to fit in the temporary buffer. This requires all buffers to
have matching sizes to get the same resulting name everywhere.

By adding omp_get_initial_device and omp_get_num_devices builtins for
C, C++, and Fortran, the following can be achieved:
* By making them pure, multiple calls can be avoiding in some cases.
* Some comparisons can be optimized at compile time.
omp_get_initial_device will be converted to omp_get_num_devices for
consistency; note that OpenMP 6 also permits omp_initial_device (== -1)
as value.
