The condition that enabled ELOG to do something has been broken since
bug 279212 landed two years ago, because MAKEFLAGS doesn't contain the
dash for flags, so looking for "-s" never did anything.
Bug 1560527 changed the condition to !BUILD_VERBOSE_LOG, which as of the
previous commit, does work. This would restore the old behavior, at the
expense of build time, since it involves wrapping in a shell script,
which is not necessarily desirable (and hasn't been done for two years
now)

With clang-cl and PGO enabled, toolchain.configure automatically turns
on LTO for compatibility with MSVC. However, MOZ_PGO is set for both the
profile-generate and profile-use builds in a 3-tier PGO setup via
imply_option(), but we only want LTO enabled for the profile-use build
(see bug 1483778).
For 1-tier PGO builds, which are still used by local developers, MOZ_PGO
will be set and --enable-profile-generate will be unset, so LTO will be
automatically enabled. The profiledbuild target in make is responsible
for disabling MOZ_LTO on the profile-generate build.
For 3-tier PGO builds, MOZ_PGO will still be set, so we can skip setting
LTO in configure when --enable-profile-generate is set.

This is a simple mach command that imports a PR from a whitelisted set
of github repositories into the local m-c clone. It works by downloading
the .patch file from github, splitting the different commits, and
applying those commits to the local repo via the `patch` tool and git/hg
commit. It optionally allows filing a bug or providing a bug number, and
specifying a reviewer.
This is one part of a larger workflow that facilitates landing
contributor patches into m-c when those patches are submitted as PRs.
Other components of the workflow (to be added in the future) will make
it easier to actually test and land the patch.

We've been relying on frame pointers being indirectly enabled via things
like --enable-profiling for some time, but this doesn't scale because
some things may want frame pointers while wanting --disable-profiling.
So we move MOZ_FRAMEPTR_FLAGS to python configure and add a new option
to decide whether to enable frame pointers or not.

Bug 1394825 bumped the minimum version of clang we use on automation,
for the base toolchain jobs, and there's a libclang test for bindgen,
but we should reject the compiler in the first place.
The check to do that works in both C and C++, contrary to the original
3.6 test that was checking a C++ feature ; the test was later changed
for 3.9, using a check that would have worked in both C and C++, but
the C exception was left around. We remove it now.

The current logic is that if the compiler somehow uses gold rather than
BFD ld by default, we let it, but if it uses BFD ld, we default to lld.
When doing Android builds, the compiler finds the linker in the NDK, and
the default `ld` binary is gold. So we currently end up using fold for
Android builds.
Here, we change the logic such that we use lld when the default linker
the compiler uses is either BFD ld or gold. We can't go with "is not
lld" because the other possible kind, ld64, is what we actually want to
use on mac, since lld doesn't support mach-o fully just yet.

The current setup for bindgen relies on either finding clang/libclang
from the output of llvm-config, or from the paths given via the
configure flags --with-clang-path/--with-libclang-path.
One _very_ common problem is that the llvm-config we end up using does
not correspond to the clang used for compilation, which has some
undesirable side effect, like failing to build.
So instead of relying on llvm-config, we do the following:
- when the compiler is clang, we just use that
- when the compiler is clang-cl, we use clang from the same directory
- otherwise, we either try to find clang in PATH, or rely on
--with-clang-path.
Once clang is found, we try to deduce the location of the corresponding
libclang via the output of `clang -print-search-dirs`, or rely on
--with-libclang-path.

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.

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.
