d16d251e20 Move MAY_BE_REF check into COPY_SSA_OBJ_TYPE 
ZEND_ASSIGN is not the only place where this is relevant, so
handle it generically inside COPY_SSA_OBJ_TYPE instead.

b08aac0451 Fix inference for assignment of known object to reference 
We cannot retain the ce information in that case, we have to
assume the ce may change indirectly through the reference.

ef80dcb80b Fix GH-8074: Wrong type inference of range() result 
If either the first or second operand of `range()` may be a string, we
must not exclude the possibility that the result may be an array of
longs.

Closes GH-8131.

0b3a937670 Fix GH-7759: Incorrect return types for hash() and hash_hmac() 
`hash()` and `hash_hmac()` never return `false`; only `hash_file()` and
`hash_hmac_file()` return `false` in case the data cannot be read.

Closes GH-7760.

coming from old_pred as well.

2e29817005 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.
