Piccolo low power mode support

For version 9 VisSim will

For version 9 VisSim will have a Low Power Mode setting in the MCU Configuration screen for Piccolo like it has for MSP430. But it is quite simple to enter IDLE mode by using an External Function block, set to asm("IDLE"), in a compound block configured to run as a background task. This puts the processors into low power IDLE mode between RTOS/Controller interrupts, and after other idle loop tasks have been run.
The attached diagram below shows this in a Piccolo Launchpad blink example.
