7892bfc18a Bug 1554989 - Fix implicit checker on inheriting constructors r=andi
Inheriting constructors are implicitly introduced via a using-declaration.
Since the C++ grammar doesn't allow attributes on using-declarations, it
is currently impossible to add MOZ_IMPLICIT to implicit inheriting
constructors.

This commit changes the AST matcher such that it ignores inheriting
constructors altogether. If they are inheriting from an implicit inherited
constructor, that constructor's check should be enough to ensure that no
constructors are unintentionally implicit.

e52ded1092 Bug 1553065 - Move profile-use mozconfig info into common mozconfigs; r=firefox-build-system-reviewers,chmanchester
The 3-tier PGO builds used a separate mozconfig called 'profile-use' for
the final tier. This created a problem when it rode to beta, since the
same mozconfig was used for all trees, which meant we ended up with
nightly branding on beta builds.

With the PGO-enabling logic in common mozconfigs, we can enable it by
setting the MOZ_PGO_PROFILE_USE environment variable from the task
definition. All of the final-tier PGO builds now use the nightly, beta,
etc mozconfigs like before, so branding should be intact.

2b3a15afe9 Bug 1542746 - use a static MOZ_PROFILE_ORDER_FILE; r=nalexander,chmanchester
We're planning on switching to IR-based profiling, so we can't use the
frontend-based instrumentation to collect the order in which functions
are executed...at least not during the build itself.  Performance tests
indicate that not having the order information decreases performance
significantly.  So we're going to check in static files for Win32 and
Win64 and use those to perform the ordering.  It's OK if these files are
slightly out of date; as of this writing, builds that generate and then
use these files complain that ~1/3 of the functions can't be found (!).
We're just trying to do something slightly smarter than whatever the
linker default is.

93a44ee14e Bug 1553972 - make --with-pgo-profile-path take a directory; r=nalexander
e10s profiling or IR-based PGO instrumentation will both produce
multiple `.profraw` files that need to be handled in some way.  Since
clang's `-fprofile-generate` option takes a directory, it seems fitting
to make `--with-pgo-profile-path` mirror that by taking a directory, and
letting `merge_profdata.py` deal with whatever files it might find in
said directory.

37d0db29a9 Bug 1551690 - be more specific about the LLVM target on OS X; r=nalexander
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.

1722aa9085 Bug 1552425 - re-disable e10s when generating PGO profile data to fix speedometer perf regression r=froydnj
Bug 1548941 restricted under which circumstances we allow the
browser.tabs.remote.autostart pref to turn off e10s. The PGO profileserver.py
script relied on the unittest-required user.js prefs collection to turn off
e10s (see also bug 1196094) via this pref. For PGO builds, we do not set the
MOZ_DISABLE_NONLOCAL_CONNECTIONS env var, which meant that we stopped
honouring the pref to turn off e10s. Unfortunately, this meant that
e10s was inadvertently now switched on for the pgo profiling, which
negatively impacted speedometer on PGO builds (and possibly other tests).

All this change does is re-disable e10s for PGO profiling. We should
investigate how to turn e10s on "properly" for PGO, but we can do that in
bug 1196094, without taking this temporary regression, especially as 68
branches.

e10c38f6f4 Bug 1529002 - Update cbindgen. r=boris
We need this to auto-generate the copy-constructor for TransformOperation,
without which the patch wouldn't build.

This is better than failing with obscure rust errors later on.

85925b5be6 Bug 1547196 - remove rustup wrapper from rustc as well as cargo; r=glandium
Having `rustc` be `rustup`'s wrapper for `rustc` means that we may
silently honor `rustup`'s override mechanisms.  We noticed this first on
OS X, where we use the "real" `cargo` but `rustup`'s `rustc` wrapper,
and problems ensued when `cargo` thought it was using one version of
`rustc`, but actually wound up using something different.

It seems better to avoid silently interposing `rustup`'s toolchain
override mechanisms everywhere, rather than having to special-case OS
X.  So let's factor out a general mechanism for removing the wrappers
`rustup` provides and use that for both `rustc` and `cargo`.  The tests
need adjusting because we weren't triggering the unwrapping cases
before; we don't yet test the case where we really do need to unwrap.
That test can be left for a future patch.
