It made sense when we did have problems with the one shipped with clang
and needed an explicitly newer version, but that hasn't been true in a
while. On the contrary, we're now using a version older than clang for
no reason other than having forgotten to update it.

The change happened 2 years ago in bug 1571562, which means the script
hasn't hit a llvm-dsymutil crash since then (we would have noticed that
it doesn't produce reproducers if we had recurring llvm-dsymutil crashes).
So before removing the script, fix it, so that if we do need to dig it
up from history, we don't pull a broken version.

Local builds don't use it, and currently the only builds that happen on
macs on automation are not using the clang toolchain, so they're not
going through the first condition, and the remainder of the mozconfig
is essentially no-ops (plus, the only builds on macs on automation that
do use mozconfigs at all are rusttests, for which those settings wouldn't
matter anyways).
Meaning in practice, the mozconfig is not doing anything useful.

In the case of toolchain tasks, the tooltool download script already
extracted the SDK in $MOZ_FETCHES_DIR, so no adjustment was required.
Only a Firefox mozconfig needs adaptation.

And don't set it via mozconfig. The default to /System/Library/PrivateFrameworks
may also not have matched the used SDK previously, so the new default is
better.

they likely won't), and to fix the path on the future Windows PGO

The remaining uses all need adjustements to in-tree mozconfigs, so they
all need to be done at once.
However, to make things slightly more intelligible, we do this in two
steps. This is step 1: we modify the use_toolchain transform to take care of
the transformation, while keeping the task definitions intact, so that
we only deal with mozconfig and build script adjustements here.

We need a fix from `cctools-port` master for cross-language LTO builds
to work properly on the Mac. Rather than cherry-picking yet another
commit, which would have to deal with a updated `ld64` upstream, we've
opted to go ahead and update directly to upstream.
This choice brings about some significant build changes, as TAPI support
has moved to a different library that is not easily buildable directly.

Our current OS X builds use `--target=x86_64-darwin11` (which
corresponds to OS X 10.7). This target is problematic for two reasons:
* We're actually targeting for OS X 10.9 (`MACOSX_DEPLOYMENT_TARGET`);
* It's slightly different from the default Rust target.
Let's address these problems in reverse order: differences from the Rust
target are bad, because the `--target` we provide to `clang` and the
Rust target find their way into LLVM bitcode files and the linker will
refuse to link together bitcode files that have incompatible targets.
Why are the two incompatible? The current `--target` doesn't have a
"vendor" in triple-speak, whereas the Rust one has "apple" as the
vendor (`x86_64-apple-darwin`) We therefore need to change the
`--target` we pass to `clang` to have a vendor of "apple".
This need is behind the {init,toolchain}.configure changes,
but it has ramifications elsewhere, because `clang` looks for
`--target`-prefixed build tools. So we have to change the `--target`
for cctools to get the right tool prefixes and we have to change the
`--target` for building clang ourselves so that *those* builds can find
the newly renamed cctools.
Once we've done, that's really enough; we don't *need to address the
first problem: While the `--target` might be `x86_64-apple-darwin11`,
both `clang` and `rustc` will dynamically choose the target triple that
eventually lands in LLVM bitcode files based on
`MACOSX_DEPLOYMENT_TARGET`, which we set in all builds. But the current
target is slightly misleading, and the cctools don't need to be prefixed
with a particular Darwin version, since they work for all Darwin
targets. Let's just drop the "11" from the `--target` and eliminate a
little bit of confusion.
