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.

Remove code to fall back to llvm-gcc for i386 kexts.

More cleanups to follow in separate commits....

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

 - 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.

Patch by Jonathan Schleifer!

Allow to pass from syntactic form of InitListExpr to semantic form (just as viceversa). No functionality change.

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.
Fixes PR14292.

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.

[Windows] Fix mangling of number literal '0'

Do this by making the mangleNumber(APSInt) overload look like
the int64_t version. (The latter should probably just delegate
to the former).

Test from Evgeny Eltsin!
