025f4c0fad Walk down the dominator tree instead of the control flow graph. That means 
that we can't modify the CFG any more, at least not until it's possible
to update the dominator tree (PR217).

b74ed07bfd Adding dllimport, dllexport and external weak linkage types. 
DLL* linkages got full (I hope) codegeneration support in C & both x86
assembler backends.
External weak linkage added for future use, we don't provide any
codegeneration, etc. support for it.
