See the comment-block at the top of MIPSAssembler.cpp for
implementation overview.

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.
