*	Compile-time choice between 16 bit and 32 bit integers for the filters. 32 ↵	Jens Arnold	2008-11-19
\| \| \| \| \| \|	bit filters are faster on ARMv4 (with assembler code), so use them there. Nice speedup on PP and Gigabeat F/X. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@19140 a1c6a512-1295-4272-9138-f99709370657

	assembly filter vector math for ARM. Both make use of the fact that the first argument of the vector functions is longword aligned. * The ARM version is tailored for ARM7TDMI, and would slow down arm9 or higher. Introduced a new CPU_ macro for ARM7TDMI. Speedup for coldfire: -c3000 104%->109%, -c4000 43%->46%, -c5000 1.7%->2.0%. Speedup for PP502x: -c2000 66%->75%, -c3000 37%->48%, -c4000 11%->18%, -c5000 2.5%->3.7% git-svn-id: svn://svn.rockbox.org/rockbox/trunk@15302 a1c6a512-1295-4272-9138-f99709370657
