Tighten the constraints for warning about NOPs for the MSP 430 ISA, so NOPs are only inserted/warned about when needed. Specifically: 430 and 430x ISA require a NOP after DINT. Only the 430x ISA requires NOP before EINT. Only the 430x ISA requires NOP after every EINT. CPU42 errata.
* config/tc-msp430.c (is_dint): New.
(is_eint): New.
(gen_nop): New.
(warn_eint_nop): New.
(warn_unsure_interrupt): New.
(msp430_operands): Determine the effect MOV #N,SR insns have on
interrupt state.
Only emit NOP warnings for 430 ISA in certain situations.
(msp430_md_end): Only warn about an EINT at the end of the file
if NOP warnings are enabled.
