When template deduction fails on a derived class, try a template deduction on
the base class.  If the base class deduction succeeds, use those results.  If
it fails, keep using the results from the derived class template deduction.

This prevents an assertion later where the type of deduction failure doesn't
match up with the template deduction info.

Force C89 for c-index-test.c

MSVC supports only C89, so it is important to keep c-index-test.c
buildable with C89.  However, Clang defaults to C99, so while building
Clang with Clang one can introduce C99 constructs into c-index-test.c
without noticing.

Thanks to Nakamura Takumi for helping with MSVC bits.

When deciding whether to convert an array construction loop into a memcpy, look
at whether the *selected* constructor would be trivial rather than considering
whether the array's element type has *any* non-trivial constructors of the
relevant kind.

Driver/Darwin: The -arch argument values aren't exactly the arch names from a

 - Translate the special case of powerpc to its expected -arch name.

Set TLSSupported to false on Haiku.

Haiku does not support this (yet). Leaving it set to true leads to
configure scripts detecting __thread being available and Clang emitting
code for it, resulting in binaries the runtime_loader will refuse to
load.

LiteralSupport: Don't overflow the temporary buffer when decoding invalid string parts.

Instead just use a dummy buffer, we're not going to use the decoded string anyways.

Fix a bug I found while preparing my devmtg talk: When passing NULL to a
function that takes a const Foo&, where Foo is convertible from a large number
of pointer types, we print ALL the overloads, no matter the setting of
-fshow-overloads.

There is potential follow-on work in unifying the "print candidates, but not
too many" logic between OverloadCandidateSet::NoteCandidates and
ImplicitConversionSequence::DiagnoseAmbiguousConversion.
