MSP430: Don't save all callee-saved regs in non-leaf interrupt functions
Previously, all callee-saved regs would unconditionally be saved
in interrupt functions that call another function.

* config/msp430/msp430.c (msp430_preserve_reg_p): Don't save
callee-saved regs R4->R10 in an interrupt function that calls another
function.
