Subject: [PATCH 4/8] Fix _mm_loadu_si32 detection for vendored Clang.
Apple uses different __clang_major__ version numbers than upstream,
so our test did not work.
This caused compilation failures with, e.g., XCode 10.1, which
reports __clang_major__ as 10 despite being forked from upstream's
7.0 branch.
Fixes #2369

Subject: [PATCH 5/8] meson: Use pkgconfig generator
It is much less error prone because Meson can detect dependencies
automatically. As bonus Meson will also generate the opus-uninstalled.pc
file.
