The ARM EABI specifies that 64 bit integers should be 8 aligned; remove our incorrect setting of 4 alignment. This has no actual effect since it only set the alignment for the 'abi_ullong' and 'abi_llong' types, which are used only inside code which is MIPS-specific, but it will avoid problems later if we use the types elsewhere.
