* Merge of the "volatile" branch:xleroy2012-02-041-81/+0
| | | | | | | | | | | | - 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. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@1814 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
