peter klausler f6aac0dd4d [flang] Fix DOT_PRODUCT for logical
A build-time check in a template class instantiation was applying
a test that's meaningful only for numeric types.

Peter Klausler a5a493e192 [flang] Speed common runtime cases of DOT_PRODUCT & MATMUL
Look for contiguous numeric argument arrays at runtime and
use specialized code for them.

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.

peter klausler 5e1421b22f [flang] Implement MATMUL in 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.
