I was able to reproduce the failure to apply llvm-dsymutil on the last
mozilla-central revision before debug info was temporarily disabled for
rust, and validated that the problem was gone in clang 4.
After some bisection, r289565 was identified as having fixed the
problem, which, reading the commit message, makes sense.
It was however not possible to simply cherry-pick, because of multiple
code changes between 3.9 and 4. However, apart from the volume of
conflicting changes, it was more or less straightforward to backport.
Interestingly, the patch for r313872 was relying on changes from
r289565, which is why it required a variant specifically for 3.9, but
now we can use the same patch as for other versions. Well, except
there's a small difference in the context, and build-clang.py doesn't
allow fuzz, so we manually edit the patch to remove that line from the
context.

Before, the build root was not in a Docker cache or volume. With
current Docker works, that meant AUFS. We know AUFS is slow under
I/O load and can cause random failures due to missing data after
writes.
This commit changes the build root to a known Docker volume, which
will be backed by EXT4 and won't have the problems of AUFS.

32-bit clang-cl.exe was looking specifically for HostX86\x86\link.exe, which doesn't exist in our automation package. Make it look in HostX64\x86 instead.
This is an ugly hack and it would be preferable to just use a 64-bit compiler (bug 1414287).
In a proper VS install, the path to cl.exe looks like:
...\VC\Tools\MSVC\14.11.25503\bin\HostX64\x64\cl.exe
In our automation, the path is just:
...\VC\bin\HostX64\x64\cl.exe
Clang tries to do some sanity-checking to make sure that the cl.exe it finds is the Microsoft compiler and not some other program. But the checks are a little too strict for us, so just look for "bin\Host*\*\cl.exe".
Ideally, we'd backport it to the clang 4 toolchain too, but that results
in silently(!) missing crash symbols for libxul.

Using /home/worker is the build directory has a 30% talos performance
loss, because test machines has a /home mount directory.

shutil.copy2() will fail if the destination directory doesn't exist.
Switch to copy_tree() instead so we don't need to worry about the
error cases of copy2() and copytree().

We're soon going to build multiple versions of clang and gcc for linux,
and we need to differentiate them. Furthermore, there is a need for the
base-toolchains builds to use a fixed version of clang and gcc. So
rename the clang and gcc toolchain jobs to include their version, add
aliases to satisfy all existing jobs, and adjust the base-toolchains
jobs to use the explicit version.

rename : build/build-clang/clang-linux64.json => build/build-clang/clang-3.9-linux64.json
rename : taskcluster/scripts/misc/build-gcc-linux.sh => taskcluster/scripts/misc/build-gcc-4.9-linux.sh
Using /home/worker is the build directory has a 30% talos performance
