compiler: Implement interface calls
...
This is a big combined change. Other changes in this commit:
* Analyze makeinterface and make sure type switches don't include
unnecessary cases.
* Do not include CGo wrapper functions in the analyzer callgraph.
This also avoids some unnecessary type IDs.
* Give all Go named structs a name in LLVM.
* Use such a named struct for compiler-generated task data.
* Use the type and function names defined by the ssa and types
package instead of generating our own.
* Some improvements to function pointers.
* A few other minor improvements.
The one thing lacking here is interface-to-interface assertions.

Add AVR support

This requires support in LLVM, as AVR support is still experimental. For
example, in bindings/go/build.sh, add
-DLLVM_EXPERIMENTAL_TARGETS_TO_BUILD=AVR to cmake_flags.

compiler: Set actual initializer for global variables
...
In the Go SSA, global variables are initialized in the init() function
instead of declaring them in the global itself. Work around this oddity
by simply setting the correct initializer when we find this global.
This should produce more efficient code, both in RAM and code size.
Apparently LLVM didn't optimize it away on it's own.
