ARCH_ARM_HAVE_NEON is only ever defined to true, so test for that.
For the NEON function to be used, the file has to include
machine/cpu-features.h so that __ARM_HAVE_NEON is defined.

See the comment-block at the top of Aarch64Assembler.cpp
for overview on how AArch64 support has been implemented
In addition, this commit contains
[x] AArch64 inline asm versions of gglmul series of
functions and a new unit test bench to test the
functions
[x] Assembly implementations of scanline_col32cb16blend
and scanline_t32cb16blend for AArch64, with unit
test bench

I was fed-up with the constant conflicts in Eclipse
with the "libutils" version.
Also fix a few copyright notices.

This patch attempts to remove the generation of libpixelflinger_armv6,
which contains the ARMv6 specific object - rotate90CW_4x4_16v6.o. But,
libpixelflinger_armv6 is not actually used by other projects.

This is a shortcut for the needs descriptor
00000077:03515104_00000000_00000000. It requires blending a single 32-bit
colour value into a 16-bit framebuffer.
It's used when fading out the screen, eg. when a modal requester pops-up.
The PF JIT produces code for this using 24 instructions/pixel. The NEON
implementation requires 2.1 instructions/pixel. Performance hasn't been
benchmarked, but the improvement is quite visible.
This code has only been tested by inspection of the fading effect described
above, when press+holding a finger on the home screen to pop up the
Shortcuts/Widgets/Folders/Wallpaper requester.
Along with the NEON version, a fallback v5TE implementation is also provided.
This ARM version of col32cb16blend is not fully optimised, but is a reasonable
implementation, and better than the version produced by the JIT. It is here as
a fallback, if NEON is not available.
A better fix would be to banish this qemu tracing stuff from libhardware
and also banish it from non-emulator builds, but this at least gets the
minimal build building again.
