main: use GOPATH from the environment
...
Be more compatible with the Go toolchain by setting GOPATH in the same
way. This makes it possible to flash and run examples from the standard
GOPATH instead of only from the source tree.

nrf: fix off-by-one in modulo of runtime.ticks
...
This code:
foo & 0xffffff
Is equivalent to this code:
foo % 0x1000000
However, to drop the high 8 bits, this calculation was used:
foo % 0xffffff
This is far more expensive (and incorrect), as it needs an actual modulo
operation which increases code size and probably reduces speed on a
Cortex-M4 and needs library functions for a Cortex-M0 increasing code
size by a much bigger amount.

all: change special type __volatile to pragma //go:volatile
...
This is one step towards removing unnecessary special casts in most
cases. It is also part of removing as much magic as possible from the
compiler (the pragma is explicit, the special name is not).

Apparently -Oz without inliner is the fastest, probably because it

running it? Can we control this?

The fact it was called Parse() is more of a historical accident, as the
compiler started out using the Go AST directly instead of Go SSA.

compiler: expand small structs
...
Use fields of small structs (3 or less fields when flattened
recursively) directly as parameter values.
Advantages:
* Code size is slightly reduced, both on unix and nrf.
* AVR can finally deal with struct parameters - at least the small
ones. examples/test now compiles. A real fix for struct parameters
should go into upstream LLVM, but this is a nice win.
