runtime: fix hashmap lookup of entries at position > 8
...
Bigger hashmaps (size > 8) use multiple buckets in a chain. The lookup
code looked at multiple buckets for a lookup, but kept checking the
first bucket for key equality.

compiler: correctly generate global hashmaps of size > 8

Static map generation used the last bucket instead of the first bucket
in the chain, which caused lots of missing entries in hashmaps with
multiple buckets (size > 8).

compiler: optimize runtime.stringToBytes calls
...
This optimization makes sure the following pattern doesn't do a heap
allocation (assuming Write doesn't modify the slice):
var w *machine.UART = ...
w.Write([]byte("foo"))
As long as Write doesn't modify the slice and LLVM can detect this, a
call to runtime.stringToBytes with the necessary allocation + copy is
avoided.

A few changes to make sure compiler-rt is correctly compiled (and
doesn't include host headers, for example).
This improves support for AVR, but it still doesn't work. Compiler-rt
itself doesn't really work for AVR either.

compiler: fix interface calls for big underlying values
...
When the underlying value of an interface does not fit in a pointer, a
pointer to the value was correctly inserted in the heap. However, the
receiving method still assumed it got the underlying value instead of a
pointer to it leading to a crash.
This commit inserts wrapper functions for method calls on interfaces.
The bug wasn't obvious as on a 64-bit system, the underlying value was
almost always put directly in the interface. However, it led to a crash
on the AVR platform where pointer are (usually) just 16 bits making it
far more likely that underlying values cannot be directly stored in an
interface.

Make sure package initializers show up in backtraces, as they should. In
