c011890764 Push clobbered neon registers on the stack 
According to the calling convention, the registers q4-q7 should be
preserved by functions. The caller (generated by the compiler) could
be using those registers anywhere for any intermediate data.

Functions that use more than 12 of the qX registers must push
the clobbered registers on the stack in order to be able to restore them
afterwards.

In functions that don't use all 16 registers, but clobber some of
the callee saved registers q4-q7, one or more of them are remapped
to reduce the number of registers that have to be saved/restored.

This incurs a very small (around 0.5%) slowdown in the decoder and
encoder.

811c647c0e Remap registers to avoid clobbering the neon registers q4-q7 
According to the calling convention, the registers q4-q7 should be
preserved by functions. The caller (generated by the compiler) could
be using those registers anywhere for any intermediate data.

Functions that use 12 or less of the qX registers can avoid
violating the calling convention by simply using other registers instead
of the callee saved registers q4-q7.

This change only remaps the registers used within functions - therefore
this does not affect performance at all. E.g. in functions using
registers q0-q7, we now use q0-q3 and q8-q11 instead.

8f88f60637 Explicitly sort the files in mktargets.py 
This avoids spurious changes to the targets.mk files when mktargets
is rerun on different platforms and different file systems.

In particular, OS X seems to mostly return files sorted
alphabetically, case insensitively, while they are returned in
a file system specific order on linux.
