When FINDLOC() can't find its target value among the unmasked array
elements, it must return a zero result. Its implementation doesn't
sufficiently distinguish a zero result from a hit in an array with lower
bound(s) less than one. Fix by adding a flag to distinguish the case
with no hits from cases with hits.
Fixes llvm-test-suite/Fortran/gfortran/regression/findloc_6.f90.
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.

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.

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.

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.
