Refactors itx into separate 10, 12 bit functions to prevent conditional
jumps.

Use numerical GPR references everywhere for consistency.

Give some constants a more explicit name to avoid confusion when 12bpc
support is added.

Realign the buffer if neccessary to maintain 64-byte alignment.

Also make some minor optimizations to the AVX2 asm.

Fixes segfaults on Windows.

Exchange clang-7 with clang in build-debian-werror as clang-7 is only
available in buster.

This fixes building with MSVC (and probably old GCC too) after
9636af88.

That commit made src/cpu.h include src/internal.h. src/internal.h
includes stdatomic.h and thus requires declaring the dependency on
stdatomic_dependencies.

Instead of adding that dependency in all other build targets that
include src/cpu.h (most tests and tools), avoid leaking the dependency
in this particular header.

Meson's dynamic check is unreliable when additional compiler flags are
passed via CFLAGS. For example '-fprofile-instr-generate' in oss-fuzz'
coverage build. Fixes #370.

Causes collisions with stdbool.h on some systems.

Having the exact commit hash in the logs helps with debugging.

Fixes #369.

This reverts commit e5331417.

Causes issues when the sample has both 8 and 16 bit content.
