Add Builtins.def attribute for "can be a constant expression".
- Enabled for builtins which are always constant expressions
(__builtin_huge_val*, __builtin_inf*, __builtin_constant_p,
__builtin_classify_type, __builtin___CFStringMakeConstantString).
Added Builtin::Context::isConstantExpr.
- Currently overly simply interface which only works for builtins
whose constantexprness does not depend on their arguments.
CallExpr::isBuiltinConstantExpr now takes an ASTContext argument.
