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.

API, implementation, and basic tests for the transformational
reduction intrinsic function DOT_PRODUCT in the runtime support
library.

Implement the reduction transformational intrinsic function NORM2 in
the runtime, using infrastructure already in place for MAXVAL & al.
Differential Revision: https://reviews.llvm.org/D102024
The single source file reduction.cpp is a little large in
terms of both source lines and generated text bytes, so
split SUM, PRODUCT, FINDLOC, and MAXLOC/MAXVAL/MINLOC/MINVAL
off into their own C++ source files that share a set of
implementation function templates now in a common header.

Define APIs for, and implement, these three more recently-introduced
standard reduction transformational intrinsic functions to the runtime.

Move #include <complex.h> to complex-reduction.h, where
it is needed in MSVC builds.
Exclude code that requires a native 128-bit integer type from
compilation by MSVC.

Add runtime APIs, implementations, and tests for ALL, ANY, COUNT,
MAXLOC, MAXVAL, MINLOC, MINVAL, PRODUCT, and SUM reduction
transformantional intrinsic functions for all relevant argument
and result types and kinds, both without DIM= arguments
(total reductions) and with (partial reductions).
Complex-valued reductions have their APIs in C so that
C's _Complex types can be used for their results.
Some infrastructure work was also necessary or noticed:
* Usage of "long double" in the compiler was cleaned up a
bit, and host dependences on x86 / MSVC have been isolated
in a new Common/long-double header.
* Character comparison has been exposed via an extern template
so that reductions could use it.
* Mappings from Fortran type category/kind to host C++ types
and vice versa have been isolated into runtime/cpp-type.h and
then used throughout the runtime as appropriate.
* The portable 128-bit integer package in Common/uint128.h
was generalized to support signed comparisons.
* Bugs in descriptor indexing code were fixed.
