This patch adds support for struct return values to the MSP430 target backend. It also reverses the order of argument and return registers in the calling convention to bring it into closer alignment with the published EABI from TI. Patch by Andrew Wygle (awygle).

The AVR architecture does not have the concept of unaligned loads - all loads/stores from all addresses are aligned to one byte.
