When building Mesa against a recent LLVM 10 with C++11, the build fails
if the AMD common code is built as well due to "std::index_sequence"
being undeclared.
LLVM requires a minimum of C++14.

Control-flow enforcement technology is a new instructions on x86
processors to denote where indirect jumps can land. Gcc auto adds
the instruction (which encodes as a NOP on older CPUs) to entrypoints
but assembler files need manual adding. This adds it to all the
entry points in the mesa x86/x86-64 assembler files.
This will only happen if mesa is built with the -fcf-protection flag
to gcc as some distros are wanting to do.

The asm code expects a specific kind of implementation, but Android
uses something different (emutls).
Turns out mesa has a fallback with pthread_getspecific, with an
optimizaiton if only a single thread is used. emutls also uses
getspecific, so lets just use the optimized mesa implementation.

This reverts commit 5157a42765.
There is a meson bug that causes llvm to always be statically linked,
which is obviously not what we want. I haven't had time to look into it
yet, but for now let's just revert it.
Previously, on systems where multiple versions of Python 3 (e.g. 3.6 and 3.7)
are installed, wrong version of Python 3 could have been used.
The proper fix requires availability of path() method in Meson's python
module, which has been added in Meson 0.50:

Meson has support for using cmake as a finder for some dependencies,
including LLVM. Using cmake has a lot of advantages: it needs less meson
maintenance to keep working (even for llvm updates); it works more
sanely for cross compiles (as llvm-config is a compiled binary not a
shell script). Meson 0.51.0 also has a new generic variable getter that
can be used to get information from either cmake, pkg-config, or
config-tools dependencies, which is needed for cmake. We continue to
support using llvm-config if you don't have cmake installed, or if cmake
cannot find a suitable version.

The dri2 winsys also uses libdrm (and you can only enable dri3 if
you enable dri2), and the drm winsys only requires libdrm.
So if any winsys is enabled you can also enable the drm winsys, and
since we always want at least one winsys we can always enable it.
I removed the check for the drm platform for VA and OMX since they
do not care anymore. Since we still check for one of r600g, nouveau
or radeonsi, we are guarantueed to still only enable it by default
in a configuration that requires libdrm anyway. So for people using
va=auto, we don't suddenly start requiring libdrm were we did not
before.
This supersedes "vl: Enable DRM by default.", which I pushed, but
rolled back because it used dep_libdrm before its definition.

If libdrm is found the pipe loader enables drm anyway, and that is
pretty much the only extra dependency this code has.
This enables creating libva display using a drm fd without having
to enable the DRM (GBM really) backend of EGL, which is completely
unrelated.
Leaving the X11 platforms alone as they would still result in the
additional inclusion of extra deps.

This roughly mirrors what we get from autotools. There's a few
differences, though:
1. The "exec_prefix" output has been dropped. Meson doesn't support
this, so it makes no sense here.
2. The "llvm-config" output has been dropped. Meson abstracts dependency
discovery a bit more than our autotools build-system does, so it's
not easy to get this information as-is.
3. HUD extra stats, SWR archs, Shared/Static libs and CFLAGS / CXXFLAGS /
LDFLAGS has been dropped. These can be inspected by "meson configure".
4. How we set defines works quite differently in our Meson build-system,
and the result isn't quite the same. In particular, the DEFINES output
has been dropped, to avoid having to refactor the code too much.
