ObjCPlusPlus as Objective-C classes. Really the
compiler should say they have Objective-C runtime
class, but we should be a little more resilient
(we were refusing to find ivars in those classes
before).
Also added a test case.

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.

When an instruction match is found, but the subtarget features it
requires are not available (missing floating point unit, or thumb vs arm
mode, for example), issue a diagnostic that identifies what the feature
mismatch is.

With -fno-math-errno (the default for Darwin) or -ffast-math these library
function can be marked readnone enabling more opportunities for CSE and other
optimizations.

before running the test suite. A usage example looks like this:
test $ ./dotest.py -A x86_64 -R /tmp/x86_64 &
test $ ./dotest.py -A i386 -R /tmp/i386 &
where we would want to run the x86_64 and i386 archs concurrently but relocate the test suite to different directory
hierarchies in order not to stump on each other's intermediate files.

Fixed an issue that would happen when using debug map with DWARF in the .o files where we wouldn't ever track down the actual definition for a type when things were in namespaces. We now serialize the decl context information into an intermediate format which allows us to track down the correct definition for a type regardless of which DWARF symbol file it comes from. We do this by creating a "DWARFDeclContext" object that contains the DW_TAG + name for each item in a decl context which we can then use to veto potential accelerator table matches. For example, the accelerator tables store the basename of the type, so if you have "std::vector<int>", we would end up with an accelerator table entry for the type that contained "vector<int>", which we would then search for using a DWARFDeclContext object that contained:
[0] DW_TAG_class_type "vector<int>"
[1] DW_TAG_namespace "std"
This is currently used to track down forward declarations for things like "class a:🅱️:Foo;".

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.
