Try to interpret simple function calls in init() functions
...
This is useful for example for globals like these:
import "errors"
var MyError = errors.New("mymodule: something went wrong!")

Remove use of CGo in the runtime

CGo depends on syscall, which (in the standard library) depends on sync,
which depends on the runtime. There are also other import cycles. To be
able to use the syscall package from upstream, stop using CGo.

Switch to 16-bit typecodes and method IDs
...
It took Android some time to even hit the 64K limit for regular method
calls, so switching to 16-bit IDs should be fine for method IDs of
interfaces. At least for the time being. When this limit is ever hit,
I'll think of another way, probably involving some platform-dependent
interface code (e.g. microcontrollers won't need 64K of methods) or
detecting the limit at build time.
https://android-developers.googleblog.com/2014/12/google-play-services-and-dex-method.html
Code size isn't changed, probably because the compiler optimizes away
all method calls.

Move interface method calls in Go from LLVM IR + documentation
...
This commit moves the itfmethod call implemented directly in LLVM IR to
a Go implementation in the runtime. Additionally, it fixes variable
names to be more obvious and adds a lot of documentation to explain how
interfaces actually work in TinyGo.
Code size changes for src/examples/hello:
nrf: -144
unix: -93
I'm guessing this code size reduction is a result of removing the
'noinline' function attribute.

Rewrite init() interpretation to a real interpreter
...
Instead of mostly heuristics, actually execute the init() instruction in
an interpreter to calculate initializers for globals. This is far more
flexible and extensible, and gives the option of extending the
interpreter to other code and make it a partial evaluator.

This massively increases .data size, possibly because loads of unused

now, increase the RAM size for nrf chips (the nrf52 has 64kB of RAM).
