Implement the UNSIGNED extension type and operations under control of a
language feature flag (-funsigned).
This is nearly identical to the UNSIGNED feature that has been available
in Sun Fortran for years, and now implemented in GNU Fortran for
gfortran 15, and proposed for ISO standardization in J3/24-116.txt.
See the new documentation for details; but in short, this is C's
unsigned type, with guaranteed modular arithmetic for +, -, and *, and
the related transformational intrinsic functions SUM & al.
When compiling on aarch64 some `LDBL_MANT_DIG == 113` entries
end up trying to use `complex<long double>` for which there are
no certain specializations in `libcudacxx`. This change-set
includes a clean-up for `LDBL_MANT_DIG == 113` usage, which is replaced
with `HAS_LDBL128` that is set in `float128.h`.
`std::complex` operators do not work for the CUDA device compilation
of F18 runtime. This change makes use of `cuda::std::complex` from
`libcudacxx`.
`cuda::std::complex` does not have specializations for `long double`,
so the change is accompanied with a clean-up for `long double` usage.
Additional change on top of #109078 is to use `cuda::std::complex`
only for the device compilation, otherwise the host compilation
fails because `libcudacxx` may not support `long double` specialization
at all (depending on the compiler).
`std::complex` operators do not work for the CUDA device compilation

`cuda::std::complex` does not have specializations for `long double`,

This update allows constant folding for many 128 bit floating point intrinsics
through the library quadmath, which is only available on some platforms.

HasCppTypeFor<> used to evaluate to false always, so kind 10 and 16
variants of dot_product were not instantiated even though the host
supported 80- and 128-bit real and complex data types.
In addition, HAS_FLOAT128 was not enabling complex kind=16 variant
of dot_product. This is fixed now.
Note that the change for HasCppTypeFor<> may also affect other
functions such as matmul, i.e. kind 10 and 16 variants of them
may become available now (depending on the build host).

On targets with __float128 available and distinct from long double,
use it to support more kind=16 entry points. This affects mostly
x86-64 targets. This means that more runtime entry points are
defined for lowering to call.
Delete Common/long-double.h and its LONG_DOUBLE macro in favor of
testing the standard macro LDBL_MANT_DIG.

A build-time check in a template class instantiation was applying
a test that's meaningful only for numeric types.

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.

Define an API for the transformational intrinsic function MATMUL,
implement it, and add some basic unit tests. The large number of
possible argument type combinations are covered by a set of
generalized templates that are instantiated for each valid
pair of possible argument types.
Places where BLAS-2/3 routines could be called for acceleration
are marked with TODOs. Handling for other special cases (e.g.,
known-shape 3x3 matrices and vectors) are deferred.
Some minor tweaks were made to the recent related implementation
of DOT_PRODUCT to reflect lessons learned.
