all: add compiler support for interrupts This commit lets the compiler know about interrupts and allows optimizations to be performed based on that: interrupts are eliminated when they appear to be unused in a program. This is done with a new pseudo-call (runtime/interrupt.New) that is treated specially by the compiler.
