Section 16.9.171 says:
If X has the value zero, the result has the same value as X
So if X is -0.0, SET_EXPONENT should return -0.0.

In folding and in the runtime library for real MOD/MODULO(A,P),
detect overflow from the division A/P and return a properly signed
zero result. (When A/P overflows and both A and P are finite numbers
with nonzero P, the quotient would be a large integer when rounded to
the precision of the floating-point representation.)

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.

Add extra arguments and checks to the runtime support library so that
a call to the intrinsic functions MOD and MODULO with "denominator"
argument P of zero will cause a crash with a source location rather
than an uninformative floating-point error or integer division by
zero signal.
Additional work is required in lowering to (1) pass source file path and
source line number arguments and (2) actually call these runtime
library APIs instead of emitting inline code for MOD &/or MODULO.

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.

Move #include <complex.h> to complex-reduction.h, where
it is needed in MSVC builds.
Exclude code that requires a native 128-bit integer type from
compilation by MSVC.
