Within the body of a lambda expression, decltype((x)) for an
id-expression 'x' will compute the type based on the assumption that 'x' will be captured, even if it isn't captured, per C++11 [expr.prim.lambda]p18. There are two related refactors that go into implementing this: 1) Split out the check that determines whether we should capture a particular variable reference, along with the computation of the type of the field, from the actual act of capturing the variable. 2) Always compute the result of decltype() within Sema, rather than AST, because the decltype() computation is now context-sensitive. llvm-svn: 150347
