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.

runtime: update to avoid //go:volatile
...
There was exactly one change in the output of the smoke tests:
examples/test. However, it still runs just fine on a PCA10040.
