This configuration doesn't require any extra custom settings, since
it only uses neon intrinsics that are handled automatically by the
compiler (no external assembly).

This builds for windows on arm, with llvm-mingw. The target triplet
is named -gcc since that's how similar existing targets are named,
even though it technically runs clang (via frontends named
"$CROSS-gcc").
Assemble using $CC -c since there's no standalone assembler
available (except perhaps llvm-mc).

The largest frame is currently in choose_partitioning:
warning: stack frame size of 44156 bytes in function 'choose_partitioning'
but adding HBD amplifies other things:
warning: stack frame size of 51480 bytes in function 'dec_build_inter_predictors'
Add some padding for sanitizer and variances between compilers.

INLINE is defined as __forceinline for vs* configs, but is the
normal, compiler-discretion inline for gcc/clang configs. This
makes many functions very large when building for windows targets,
much larger than they are elsewhere.
Use '__inline' as a consistent definition to get consistent function
sizes. Although Visual Studio documentation says that 'inline' is
only available in C+ code. This is probably incorrect, since Visual
Studio 2017 accepts C99 'inline' even when passed /TC. Nevertheless,
this commit uses the recommended '__inline' for consistency.
Thanks to David Major for the diagnosis.

This time behind a compile time flag :
configure --disable-always_adjust_bpm
configure --enable-always_adjust_bpm
This should make side by side testing easier and let users of the
lib pick which way they want to go.

provides msvc-like warnings for implicit conversions from 64-bit to
32-bit types
--enable-vp9-highbitdepth still requires some work
this also skips CXXFLAGS for now as some work would be needed to cleanup
third_party/*.cc or split it from test/*.cc where it comes to flags.

The referenced bug was fixed by saving neon registers. That this had any
effect was coincidental.
Both chromium and Android build with clang and neither uses this flag.

Allows building simple targets with sane default flags.
For example, using the Android arm64 toolchain from the NDK:

--platform=android-24 --install-dir=/tmp/arm64

Each time a codec is enabled or disabled with the umbrella
--enable-vpN flag, set the encoder and decoder configurations as well.
This was done as a post-processing step but doing that lost the order of
the arguments.

Also allows use of --enable-shared when configuring for Mac OS X,
producing a bare .dylib.
Enabling the shared framework bumps the iOS deployment target to 8.0,
the minimum required to support dynamic framework deployment in apps.
When not using --enable-shared, a static library for iOS 6.0+ will still
be built.
Minimum version settings have been moved into ios-version.sh so they
can be updated in a single place.
As with the static build, unless header search paths are manually
tweaked, users must add a VPX prefix on includes, such as:
#include <VPX/vpx/vpx_decoder.h>
A module map for headers is not yet included as inttypes.h is not
modular; this means that VPX cannot be used directly in Swift code,
but can still be pulled in through an Objective-C wrapper.

This commit adds a new configure option:
--enable-better-hw-compatibility
The purpose of the configure option is to provide information on known
hardware decoder implementation bugs, so encoder implementers may
choose to implement their encoders in a way to avoid triggering these
decoder bugs.
The WebM team were made aware of that a number of hardware decoders
have trouble in handling the combination of scaled frame reference
frame and 8x4 or 4x8 partitions. This commit added asserts to vp9
decoder, so when built with above configure option, the decoder can
assert if an input bitstream triggers such decoder bug.

--disable-XXX has the effect of disabling all extensions above it, e.g.,
--disable-ssse3 disables ssse3-avx2.
