runtime/scheduler: make debugging easier + rename some functions

This shouldn't affect functionality but makes debugging a whole lot
easier. A scheduler is difficult so make it easy to debug.

Internal linkage means that symbols show up in tools like objdump, which
is very useful for debugging.

Copy printfloat() from original runtime
...
I've tried writing my own, but I couldn't make it correct in all cases.
So just copy the one from upstream for now, hopefully to be replaced at
some point.
TODO: add a printfloat32() implementation, now it just casts to float64.
This will be useful for embedded systems that sometimes have float32 but
not float64.

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.
