Nikita Popov 18b4e36df1 Move check for named params in fcall optimization earlier 
I don't think this is strictly necessary, but I think it makes
sense to check this before interpreting opline->op2.num as an
argument number.

This also adds one more has_known_send_mode() check that I had
missed before.

Nikita Popov c72e9621ce Improve type narrowing fix 
We need to explicitly model the null return type for property
accesses on non-objects.

Nikita Popov 323f3c6914 Improve file/line information for narrowing warning 
Report the file/line of the opline rather than the include location.

This should make issues like #8251 easier to debug.

Nikita Popov cf377eefa6 Don't convert assign op operand types in opcache 
This is the same change as 56b18d478e
but for ASSIGN_OP. Changing the operand type may change the error
message and can result in different behavior with operator overloading.

As with the other patch, if there is strong interest this could be
added to the DFA pass instead, with an appropriate type check.
