Before this patch, we had visitRecordInitializer() and
visitArrayInitializer(), which were different from the regular visit()
in that they expected a pointer on the top of the stack, which they
initialized. For example, visitArrayInitializer handled InitListExprs by
looping over the members and initializing the elements of that pointer.
However, this had a few corner cases and problems. For example, in
visitLambdaExpr() (a lambda is always of record type), it was not clear
whether we should always create a new local variable to save the lambda
to, or not. This is why https://reviews.llvm.org/D153616 changed
things around.
This patch changes the visiting functions to:
- visit(): Always leaves a new value on the stack. If the expression
can be mapped to a primitive type, it's just visited and the value is
put on the stack. If it's of composite type, this function will
create a local variable for the expression value and call
visitInitializer(). The pointer to the local variable will stay on
the stack.
- visitInitializer(): Visits the given expression, assuming there is a
pointer on top of the stack that will be initialized by it.
- discard(): Visit the expression for side-effects, but don't leave a
value on the stack.
It also adds an additional Initializing flag to differentiate between the initializing and non-initializing case.

This patch makes the display of member function calls more true to the user-written code by making use of the syntactical structure of the function calls.
This patch also changes the display of conventional value-based printing from arrow operator to dot operator.
This avoids the syntactical invalidness in notes previously caused by the display of & operator
(lack of parentheses and reference of rvalue)
