Modify irbloc destination mecanism. Rework API in consequence.

Fat patch here: some API have changed.

Each irbloc now affects a special "IRDst" register which is used to
describe the destination irbloc. It allows simple description of
architectures using delay slots. Architectures semantic and tcc/python
jitter are modified in consequence. LLVM jitter is disabled for now,
but should be patch soon.
