This utility routine in constant folding should return false when
a DIM= actual argument to a reduction intrinsic function has a
value that prevents folding, and true when folding can proceed.
The implementation was returning true in cases where a DIM=
argument was present but not constant.
Clarify the code and add commentary: a true result means that
there is no DIM= actual argument present, or that a DIM= argument
exists, is constant, and has a value that is in range.

Using recently established message severity codes, upgrade
non-fatal messages to usage and portability warnings as
appropriate.

A recent change that extended semantic analysis for actual arguments
that associate with procedure dummy arguments exposed some bugs in
regression test suites due to points of confusion in symbol table
handling in situations where a generic interface contains a specific
procedure of the same name. When passing that name as an actual
argument, for example, it's necessary to take this possibility into
account because the symbol for the generic interface shadows the
symbol of the same name for the specific procedure, which is
what needs to be checked. So add a small utility that bypasses
the symbol for a generic interface in this case, and use it
where needed.

Refactor the recently-implemented MAXVAL/MINVAL folding so
that the parts that can be used to implement other reduction
transformational intrinsic function folding are exposed.
Use them to implement folding of IALL, IANY, IPARITY,
SUM. and PRODUCT. Replace the folding of ALL & ANY to
use the new infrastructure and become able to handle DIM=
arguments.

Implement constant folding for the reduction transformational
intrinsic functions MAXVAL and MINVAL.
In anticipation of more folding work to follow, with (I hope)
some common infrastructure, these two have been implemented in a
new header file.
