argument instead of a result result object.
Change the reshape flang unit test to use the new interface. Also, add an
order argument to exercise the order subscript code in the rehsape runtime
routine.

When chasing down another unrelated bug, I noticed that the
implementations of various character intrinsic functions assume
that the lower bounds of (some of) their arguments were 1.
This isn't necessarily the case, so I've cleaned them up, tweaked
the unit tests to exercise the fix, and regularized the allocation
pattern used for results to use SetBounds() before Allocate() rather
than the old original Descriptor::Allocate() wrapper around
CFI_allocate().
Since there were few other remaining uses of the old original
Descriptor::Allocate() wrapper, I also converted them to the
new one and deleted the old one.

Define APIs, naively implement, and add basic sanity unit tests for
the transformational intrinsic functions CSHIFT, EOSHIFT, PACK,
SPREAD, TRANSPOSE, and UNPACK. These are the remaining transformational
intrinsic functions that rearrange data without regard to type
(except for default boundary values in EOSHIFT); RESHAPE was already
in place as a stress test for the runtime's descriptor handling
facilities.
Code is in place to create copies of allocatable/automatic
components when transforming arrays of derived type, but it won't
do anything until we have derived type information being passed to the
runtime from the frontend.

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.

Some of the regression tests are C programs that act as test harnesses
for the compiler internals as opposed to being Fortran inputs to test
the compiler in action. The former style of tests are analog to LLVM's
unittests and will not use the lit framework.
