Handle FETCH_DIM_R after FETCH_DIM_FUNC_ARG in inference

This can happen if a call is optimized, but FETCH_DIM_FUNC_ARG
cannot be converted to FETCH_DIM_R because it uses an UNUSED op2,
which is not supported by FETCH_DIM_R.

We shouldn't switch from range to no range for ZEND_DIV and instead
explicitly return an overflowing range. Otherwise the range will
not actually get updated during widening, and we'll perform
essentially infinite narrowing.

Fix return type verification with undef var

This was loading EG(uninitialized_value) into r0 rather than
FCARG1a.
However, if we fix this issue an existing test fails because
the undef var warning promoted to exception is not caught early
enough, so we need to explicitly check for the exception before
performing the type check.
