Fixes OSS-Fuzz #17895.

Intern alias old_name early

This is likely going to end up interned lateron at some point
when the new_name is referenced somewhere. However, it may be
that there are some uses that do not get interned before that.
In this case we will intern a string that already have zval
users, without updating the refcounted flag on those zvals.

In particular this can happen with something like [Foo::class],
where Foo is an imported symbol. The string it resolves to won't
get interned right away, but may be interned later.

use Foo as Bar;
$x = [Bar::class];
var_dump(Bar::X);
debug_zval_dump($x); // Will show negative refcount
class Foo {
const X = 1;
}

However, this doesn't really fix the root cause, there are probably
other situations where something similar can occur.

Add flag to disable jumptable optimization

This is useful for coverage. While it is currently safe to just
skip over the SWITCH_* opcodes, this may not be true in the future
due to opcache optimizations, so it's safer to disable emission of
SWITCH_* opcodes entirely.

Fix self::class inside constant in global scope

Previously this triggered an assertion failure. The behavior is
not quite correct, in that self::class should generate an exception
if there is no self, but returns an empty string here. Fixing that
would be a bit too intrusive for the 7.2 branch.

Partial fix for bug #75426

This does not print the exact line of the comma, but rather the line
of the previous element. This should generally be "good enough", as
the line number is

Partial fix for bug #75426

This does not print the exact line of the comma, but rather the line
of the previous element. This should generally be "good enough", as
the line number is close (off by one) to the actual issue now.
Previously it would point to the start of the array, which may be
very far away.
