Slava Zakharin d37250c9db [flang][runtime] Fixes for element size calculation.
BytesFor() used to return KIND for the size, which is not always
correct, so I changed it to return the size of the actual CppType
corresponding to the given category and kind.

MinElemLen() used to calculate size incorrectly (e.g. CFI_type_extended_double
was sized 10, whereas it may occupy more bytes on a target), so I changed it
to call BytesFor().

Additional changes were needed to resolve new failures for transformational
intrinsics. These intrinsics used to work for not fully supported
data types (e.g. REAL(3)), but now stopped working because CppType
cannot be computed for those categories/kinds. The solution is to use
known element size from the source argument(s) for establishing
the destination descriptor - the element size is all that is needed
for transformational intrinsics to keep working.

Note that this does not help cases, where runtime still has to
compute the element size, e.g. when it creates descriptors for
components of derived types. If the component has unsupported
data type, BytesFor() will still fail. So these cases require
adding support for the missing types.

New regression unit test in Runtime/Transformational.cpp
demonstrates the case that will start working properly with
this commit.

Peter Steinfeld e3550f1903 [flang] Improve runtime crash messages
Where possible, I added additional information to the messages to help
programmers figure out what went wrong.  I also removed all uses of the word
"bad" from the messages since (to me) that implies a moral judgement rather
than a programming error.  I replaced it with either "invalid" or "unsupported"
where appropriate.

Peter Klausler 77ff6f7df8 [flang] Define & implement a lowering support API IsContiguous() in runtime
Create a new flang/runtime/support.cpp module to hold miscellaneous
runtime APIs to support lowering, and define an API IsContiguous() to
wrap the member function predicate Descriptor::IsContiguous().
And do a little clean-up of other API headers that don't need to expose
Runtime/descriptor.h.

Peter Klausler 830c0b9023 [flang] Move runtime API headers to flang/include/flang/Runtime
Move the closure of the subset of flang/runtime/*.h header files that
are referenced by source files outside flang/runtime (apart from unit tests)
into a new directory (flang/include/flang/Runtime) so that relative
include paths into ../runtime need not be used.

flang/runtime/pgmath.h.inc is moved to flang/include/flang/Evaluate;
it's not used by the runtime.

Mark Leair 1dbc9b534b Fix runtime internal error with certain intrinsics that can take a scalar
result descriptor (e.g., maxloc, minloc, maxval, minval, all, any, count,
parity, findloc, etc.)

Also add a scalar case for these intrinsic unit tests.

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.

peter klausler beb5ac8b25 [flang] (NFC) Break up flang/runtime/reduction.cpp
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.

peter klausler e372e0f906 [flang] Implement reductions in the runtime
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.
