Extend annotations so that they can keep track of global variables and local variables whose address is taken.
- CminorSel, RTL: add "annot" instructions.
- CminorSel to Asm: use type "annot_arg" for arguments of "annot" instructions.
- AST, Events: simplify EF_annot because constants are now part of the arguments.
Implementation is not complete yet.
