Fariborz Jahanian 2b9fc83db5 Fixes a code gen bug related to accessing a now 
non-existing 'isa' field of a non-existing struct type
all related to legacy type definition for 'id' which we have
dropped in clang in favor of a built-in type.
(fixes radar 7470820).

Mike Stump 9a4e0128a8 Ensure we preserve line information for each trap for 
-fcatch-undefined-behavior if we aren't optimizing.  WIP.

Mike Stump e8c3b3eca4 Switch codegen for -fcatch-undefined-bahavior over to __builtin_trap 
instead of abort to improve codesize and codegen.

Mike Stump d954638f02 Implement runtime checks for undefined behavior. WIP. 
This implements a new flag -fcatch-undefined-behavior.  The flag turns
on additional runtime checks for:

  T a[I];

  a[i]    abort when i < 0 or i >= I.

Future stuff includes shifts by >= bitwidth amounts.

Douglas Gregor 7bab5ff8e7 Eliminate CXXConditionDeclExpr with extreme prejudice. 
All statements that involve conditions can now hold on to a separate
condition declaration (a VarDecl), and will use a DeclRefExpr
referring to that VarDecl for the condition expression. ForStmts now
have such a VarDecl (I'd missed those in previous commits).

Also, since this change reworks the Action interface for
if/while/switch/for, use FullExprArg for the full expressions in those
expressions, to ensure that we're emitting

Note that we are (still) not generating the right cleanups for
condition variables in for statements. That will be a follow-on
commit.
