all: rename garbage collectors 
dumb -> leaking:
  make it more clear what this "GC" does: leak everything.
marksweep -> conservative:
  "marksweep" is too generic, use "conservative" to differentiate
  between future garbage collectors: precise marksweep / mark-compact /
  refcounting.

4ecd478d82 machine: add generic board support on non-baremetal hardware 
Instead of trying to modify periperhals directly, external functions are
called. For example, __tinygo_gpio_set sets a GPIO pin to a specified
value (high or low). It is expected that binaries made this way will be
linked with some extra libraries that implement support for these
functions.

One particularly interesting case is this experimental board simulator:
https://github.com/aykevl/tinygo-play
Compiling code to WebAssembly with the correct build tag for a board
will enable this board to be simulated in the browser.

Atmel/Microchip based SAMD boards are not currently supported, because
their I2C/SPI support is somewhat uncommon and harder to support in the
machine API. They may require a modification to the machine API for
proper support.

b0e767c4a7 compiler: move global handling from ir to compiler package 
This is part of a larger rafactor that tries to shrink the ir package
and in general tries to shrink the amount of state that is kept around
in the compiler. The end goal is being able to compile packages
independent of each other, linking them together in a later stage. Along
the way, it cleans up lots of old cruft that has accumulated over the
months.

This refactor also results in globals being loaded lazily. This may be a
problem for some specific programs but will probably change back in a
commit in the near future.

here, so that further compilation will at least be safe (the result
will be discarded anyway).

e67506ee68 arm: update to avoid //go:volatile 
This change results in changes to all smoketests for Cortex-M based
chips: they get a bit smaller (32-48 bytes). I'm not sure why but
probably because the inliner made a different inlining decision. There
was a similar effect when files generated from SVD files switched to the
new volatile types so it's probably harmless.
