Add APIs, initial non-coarray implementations, and unit
tests for the intrinsic subroutines for pseudo-random
number generation.

Due to architectural variation on the C++ functions std::ceil, std::floor,
and std::trunc, diable some new Fortran unit tests for now that depending
on specifical results for IEEE floating-point edge cases of infinities
and NaNs.
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.

Create test fixture for runtime tests which enables verification
of failure cases. Test some runtime IO APIs for failure cases.
Support testing efforts in D98303. Expand on effort discussed
in D98601.

Implement INDEX in the runtime, reusing some infrastructure
(with generalization and renaming as needed) put into place
for its cousins SCAN and VERIFY.
I did not implement full Boyer-Moore substring searching
for the forward case, but did accelerate some advancement on
mismatches.
I (re)implemented unit testing for INDEX in the new gtest
framework, combining it with the tests that have recently
been ported to gtest for SCAN and VERIFY.

Move character tests to gtest, according to reviews from revision
D97349. Create a new temporary directory parallel to old runtime
unittests directory to facilitate the transition. Once patches for all
tests have been accepted using GTest, the old directory may be removed.
The new directory is required because LLVM's CMake unit test
infrastructure requires that the test depends on all source files in
the `CMAKE_CURRENT_SOURCE_DIR` directory.
