Linux and other (non-Darwin) platforms and have it use -fmath-errno by
default (for better or worse).

Darwin has seen the light here and uses -fno-math-errno by default, this
patch preserves that.

If any maintainers for a non-Linux platform would also like to opt-in to
-fno-math-errno by default, I'm happy to add folks, but we're currently
getting buts and misleading comparisons with GCC due to this difference
in behavior on Linux at least.

all instantiations of a template when we visit the canonical declaration of the
primary template, rather than trying to match them up to the partial
specialization from which they are instantiated. This fixes a bug where we
failed to visit instantiations of partial specializations of member templates of
class templates, and naturally extends to allow us to visit instantiations where
we have instantiated only a declaration.

A test for this is checking if this compiles:

    #include <float.h>

    inline bool IsFinite(const double& number) {
     return _finite(number) != 0;
    }

That depends however on either mingw or msvc being installed, and
chapuni tells me there might be issues with float.h on mingw, so
no automated test is added.

templates. In an implicit instantiation of a member class, any member
templates don't get instantiated, so the existing check which only visited
the instantiations of a defined template skipped these templates'
instantiations.

Since there is only a single declaration of a member template of a class
template specialization, just use that to determine whether to visit the
instantiations. This introduces a slight inconsistency in that we will
visit the instantiations of such templates whether or not they are
defined, but we never visit a declared-but-not-defined instantiation, so
this turns out to not matter.
