SPC codec: The inline asm 'memory' clobbers should be unneeded since the ASM either does not modify memory (only loads values), or it modifies things only other ASM blocks deal with and the operand constraints mark them as in/out/both.

Do some SPC codec optimizing for ARMv6 (as a training exercise), tweak realtime BRR for all CPU that use it, add Gaussian ASM optimization for all ARM that can use it. Add some LIKELY/UNLIKELY branch hints. On Gigabeat-S gives +22% speedup. For Gigabeat F, about +5% speedup. For less-powerful players, no real change aside possibly from branch hints.

New makefile solution: A single invocation of 'make' to build the entire tree. Fully controlled dependencies give faster and more correct recompiles.
