Ayke van Laethem 90b42799a2 machine: make machine.I2C0 and similar objects pointers
This makes it possible to assign I2C objects (machine.I2C0,
machine.I2C1, etc.) without needing to take a pointer.

This is important especially in the future when I2C may be driven using
DMA and the machine.I2C type needs to store some state.

Ayke van Laethem a5ed993f8d 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.

Ayke van Laethem 39d21e21f1 targets: simulate Circuit Playground Express in play.tinygo.org
This requires a number of changes to atsamd21 code. It's not a very
clean separation, but I couldn't come up with a better one.
