runtime: add support for math intrinsics where supported
...
In particular, add support for a few math intrinsics for WebAssembly,
but add a few intrinsics to other systems as well at the same time. Some
may be missing still but will be easy to add if needed.
This increases the performance of one example by 50% to 100% depending
on the browser: the bottleneck was the inefficient sqrt implementation.

When the target supports it, allow the (initial) heap size to be

This also changes the default heap size of WebAssembly from 64kB to 1MB.

dumb -> leaking:

marksweep -> conservative:
"marksweep" is too generic, use "conservative" to differentiate

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.

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.
