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.
