folding for MAXLOC and MINLOC.

peter klausler 3cc5d4ff8e [flang] Fix generic/specific procedure confusion
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.

peter klausler 503c085e3b [flang] Fold more reduction intrinsic function calls
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.

peter klausler 47f18af55f [flang] Fold MAXVAL & MINVAL
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.
