llvm's integrated assembler supports the AArch64 asm on darwin since
August 2014. So check $as first before using gas-preprocessor.pl via
$gas. Makes the checks specific for that the architecture specific asm
needs. PPC Altivec and AArch64 needs on ':vararg' for macro arguments.

Allow the configure tool to call the gas-preprocessor with an absolute
path when included with either the "--as" or with a separate "--gas"
option. The patch is backward compatible and will not break any current
configuration setups.
The new behavior that comes with this option can be utilized in the
following ways:
Examples:
- Just as single option that includes both the gas-preprocessor.pl and
cc/as at the same time:
$ configure --as="/opt/app/build-tools/gas-preprocessor.pl \
/Applications/Xcode.app/.../Developer/usr/bin/gcc"
- Call gas-preprocessor with a separate option in conjunction with --as:
$ configure --gas="/opt/app/build-tools/gas-preprocessor.pl" \
--as="/Applications/Xcode.app/.../Developer/usr/bin/gcc"
- Address only the the gas-preprocessor and it will automatically fall
back to as or cc whichever that's defined:
$ configure --gas="/opt/app/build-tools/gas-preprocessor.pl"
- Or if no gas-preprocessor.pl is explicitly defined, it falls back to
the old behaivor.
Some compilers when given -x objective-c will tell that they dont support
that but return success. Using a .m file instead returns proper failure in
that case
This should fix a build failure on freebsd

Based on original code by Christophe Gisquet in 2010, updated to work
with current ffmpeg APIs.
Supports grabbing a single window or an area of the screen, including
support for multiple monitors (Windows does funky stuff with negative
coordinates here).
I've moved most of the configuration to AVOptions; the input file name
is now only the string "desktop", or "title=<windowname>" to select a
single window. The AVOptions are the same as x11grab where possible.
Code has been added to support a "show_region" mode, like x11grab, which
will draw a rectangle on the screen around the area being captured.
Instead of duplicating code for paletted image handling, I make use of
the GDI API's ability to output DIB (BMP) images, which can be run
through ffmpeg's existing BMP decoder.

The vector dequantization has a test in a loop preventing effective SIMD
implementation. By moving it out of the loop, this loop can be DSPized.
Therefore, modify the current DSP implementation. In particular, the
