Don't automatically convert literal string keys to integers on
array access, as we may be dealing with an ArrayAccess object,
rather than a plain array.

Use COPY_DEREF instead of COPY_UNREF 
This fixes the behavior when the storage location of the fetch is
modified before the operand is dereferenced by the using VM opcode.

Furthermore it elimiates references as a possible return value from
*_R opcodes, which will give us more opportunities for inferences,
in particular in regard to typed properties.

95a0709935 Fix handling of ERROR zval in op1 of ASSIGN_REF 
If op1 is ERROR the behavior is to not perform any assignment and
return NULL. However, if the RHS was a by-value returning function,
we'd instead emit a notice and return the RHS as the return value
(even though the value was not assigned to anything -- the temporary
is immediately destroyed).

This normalized the behavior to always check for an ERROR in op1
first.

d877d18676 Error on by-ref assign to overloaded prop returning ref 
This error was already thrown if __get() was used -- however not
if it returned by reference. This is incorrect, because the
reference return makes no difference to a by-reference assignment,
which has reference-breaking semantics. The result was that the
assignment was accepted silently, even though it didn't do anything
(not even the value was assigned, let alone the reference).
