Change alignment macros to allow further performance optimization. Define the CACHEALIGN macros for all ARM CPUs, the used alignment size is derived from CACHEALIGN_BITS which has been defined for each supported ARM CPU with r28619. The default alignment size for ARM is set to 32 bytes as new -- not yet supported -- ARM CPUs will most probably need this alignment. To be able to differ between ARM and other CPUs a new macro called MEM_ALIGN_ATTR is introduced. This equals CACHEALIGN_ATTR for ARM, 16 byte alignment for Coldfire and is kept empty for other CPUs. MEM_ALIGN_ATTR is available system wide. From measurements it is expected that the usage of MEM_ALIGN_ATTR can give significant performance gain on ARM11 CPUs.
