b7a6430a52 Don't JIT functions with many blocks 
Avoids a stack overflow in Zend/tests/runtime_compile_time_binary_operands.php
that happens in recursive RPO calculation. We could make that code
non-recursive, but I don't think it makes sense to JIT this kind of
function in the first place.

4d1d5babde Respect optimization_level when running JIT inference 
Don't enable unsafe type inference by default -- we'll segfault on
some FFI tests.

59dfaa3f99 Fix type inference of SEND_UNPACK with empty array 
An empty array will not be turned into an array of references.
This violated the invariant than an array has values iff it has
keys.

f19dd674e0 SCCP: Fix handling of ASSIGN_OBJ_REF 
The generic BOT handling is not away of OP_DATA, so need to handle
this opcode before we get to that.

There is nothing special about the empty string in this context,
we should pass it through unchanged.

8126658444 Remove FUNC_MAY_WARN 
We are no longer constructing the local symbol table when calling
error handlers since 2f1f34952e,
which was the original motivation for having this information and
was used in an earlier version of the JIT.

bd4c9bce68 zend_func_info: Remove unnecessary type callbacks 
In PHP 8 these functions will throw on invalid arguments, so there
is no need to distinguish the error cases.

a1284b4241 Remove special handling of zero-arg funcs in func_info 
In PHP 8 we always throw on zpp failure, so we can always return the
type for the valid argument case only. We'll want to also adjust the
return type listings based on that (and drop MAY_BE_NULL/MAY_BE_FALSE
where possible).

fd23f9104a BIND_STATIC of implicit binding may be undef 
Even though we don't need it at runtime, add the BIND_IMPLICIT
flag to BIND_STATIC as well, so we can distinguish this case in
type inference.

This fixes a JIT miscompile in arrow_functions/002.phpt.

31ce1cbbb9 Func info: Fix calls to zero-arg varargs 
The num_args does not include variadics, so a "zero-arg" function
may accept additional arguments through that. No functions seem
to be affected right now, but they will be after #4175.

49a3b03e9f Implement basic variance support 
This is a minimal variance implementation: It does not support any
cyclic type dependencies. Additionally the preloading requirements
are much more restrictive than necessary. Hopefully we can relax
these in the future.
