Matt Turner 1aac47db69 Revert F16C series (MR 6774)
This reverts commit 4fb2eddfdf.
This reverts commit 7a1deb16f8.
This reverts commit 2b6a172343.
This reverts commit 5af81393e4.
This reverts commit 87900afe5b.

A couple of problems were discovered after this series was merged that
cause breakage in different configurations:

   (1) It seems that using -mf16c also enables AVX, leading to SIGILL on
   platforms that do not support AVX.
   (2) Since clang only warns about unknown flags, and as I understand
   it Meson's handling in cc.has_argument() is broken, the F16C code is
   wrongly enabled when clang is used, even for example on ARM, leading
   to a compilation error.

Eric Anholt 13ea7db760 mesa: Promote Intel's simple logging façade for Android to util/
I'm bringing up freedreno Vulkan on an Android phone, and my pains are
exactly what Chad said when working on Intel's vulkan for Android in
aa716db0f6 ("intel: Add simple logging façade for Android (v2)"):

    On Android, stdio goes to /dev/null. On Android, remote gdb is even
    more painful than the usual remote gdb. On Android, nothing works like
    you expect and debugging is hell. I need logging.

    This patch introduces a small, simple logging API that can easily wrap
    Android's API. On non-Android platforms, this logger does nothing
    fancy.  It follows the time-honored Unix tradition of spewing
    everything to stderr with minimal fuss.

    My goal here is not perfection. My goal is to make a minimal, clean API,
    that people hate merely a little instead of a lot, and that's good
    enough to let me bring up Android Vulkan.  And it needs to be fast,
    which means it must be small. No one wants to their game to miss frames
    while aiming a flaming bow into the jaws of an angry robot t-rex, and
    thus become t-rex breakfast, because some fool had too much fun desiging
    a bloated, ideal logging API.

Compared to trusty fprintf, _mesa_log[ewi]() is actually usable on
Android.  Compared to os_log_message(), this has different error levels
and supports format arguments.

The only code change in the move is wrapping flockfile/funlockfile in
!DETECT_OS_WINDOWS, since mingw32 doesn't have it.  Windows likely wants
different logging code, anyway.
