Rearrange and remove some manual register assignments, make use of pointer address increments for free on arm, and remove macros in favour of explicit inline fns. also add memory clobbers to all uses of stm in inline asm. appears to resolve issues with codeclib failing to work as expected when using ARM_ASM optimisations on targets with native position independent code (e.g. android rockbox targets, but also tremor on non-rockbox targets that has been patched with the fastermdct patches)

Fix inline asm argument. Shouldn't have much impact in practice but might save a load if gcc is clever.
