avr: link with the GCC runtime library
...
This allows the use of some compiler-generated builtins that are
hopefully compatible with LLVM. Example: println(uint8(foo))
Code size is unchanged normally but of course compiler builtins will
increase code size when actually used (for example with division).

runtime/unix: panic: call abort() instead of exit(2)
...
abort() will cause gdb to show a backtrace when running inside the
debugger, and abort() seems more appropriate anyway for critical errors.

all: basic support for the os package

The resulting binary is pretty big due to lacking optimizations
(probably because of interfaces), so that should be fixed.

all: use a custom sync package
...
The sync package is strongly tied to the runtime, so it's easier to
implement a new one. Besides, it's pretty big so it's better to replace
it.

all: rewrite sleep function
...
time.Sleep now compiles on all systems, so lets use that.
Additionally, do a few improvements in time unit handling for the
scheduler. This should lead to somewhat longer sleep durations without
wrapping (on some platforms).
Some examples got smaller, some got bigger. In particular, code using
the scheduler got bigger and the blinky1 example got smaller (especially
on Arduino: 380 -> 314 bytes).

compiler: adding a few more ignored init calls
...
These calls are generated in the JavaScript target (syscall/js and
syscall with GOOS=js), but they are not used at the moment. So ignore
them until they're needed.

compiler: fix unreachable type assert
...
The unreachable instruction is actually a block terminator so may only
be inserted at the end of a basic block. This is not always the case for
type asserts, so don't insert this instruction.
LLVM will hopefully optimize it anyway when it realizes anything after
the panic() call is unreachable.
