Merge of the "volatile" branch:
- native treatment of volatile accesses in CompCert C's semantics
- translation of volatile accesses to built-ins in SimplExpr
- native treatment of struct assignment and passing struct parameter by value
- only passing struct result by value remains emulated
- in cparser, remove emulations that are no longer used
- added C99's type _Bool and used it to express || and && more efficiently.
