Vadzim Dambrouski bdc6e663e7 [MSP430] Add SRet support to MSP430 target
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).
