Handle NULL caller_call_opline

This can happen if there is an EXIT in the call arguments, in which
case the DO_CALL opcode may be eliminated as unreachable.

Optimize VERIFY_RETURN_TYPE for TMP operands as well

Only exclude CONST operands, which use a different instruction
format (they have a return operand).

unlinked_instanceof() here, because it performs class loading,
which wouldn't be right here, I think.

Fix iterable return type optimization

Fixed bug #78341

The smart branch logic assumed b->start refers to the old offsets,
while b->start was already adjusted to the new offsets at this
point. Delay the change until later.

ZEND_DECLARE_ANON_CLASS doesn't need to skip anything now. It's immediatelly followed by ZEND_NEW.

Fix bug #78271

When cleaning nops in the dfa pass, we were always keeping the
smart branch inhibiting nop that occurs directly before the jump
instruction. However, as we skip unreachable blocks entirely, it
may happen that we need to keep a nop that occurs further back,
prior to the unreachable blocks. Account for that case now.

We should really do something about the smart branch situation,
this is very fragile...

We want the class declaration to be available while compiling the
parent class.

Remove local variables

This patch removes the so called local variables defined per
file basis for certain editors to properly show tab width, and
similar settings. These are mainly used by Vim and Emacs editors
yet with recent changes the once working definitions don't work
anymore in Vim without custom plugins or additional configuration.
Neither are these settings synced across the PHP code base.

A simpler and better approach is EditorConfig and fixing code
using some code style fixing tools in the future instead.

This patch also removes the so called modelines for Vim. Modelines
allow Vim editor specifically to set some editor configuration such as
syntax highlighting, indentation style and tab width to be set in the
first line or the last 5 lines per file basis. Since the php test
files have syntax highlighting already set in most editors properly and
EditorConfig takes care of the indentation settings, this patch removes
these as well for the Vim 6.0 and newer versions.

With the removal of local variables for certain editors such as
Emacs and Vim, the footer is also probably not needed anymore when
creating extensions using ext_skel.php script.

Additionally, Vim modelines for setting php syntax and some editor
settings has been removed from some *.phpt files. All these are
mostly not relevant for phpt files neither work properly in the
middle of the file.

Implement single-pass live range calculation

Instead of interleaving creation of live-ranges with the main
compiler code, compute them in a separate pass over the opcodes
as part of pass_two. Additionally, do not keep live ranges
synchronized during optimization in opcache and instead use the
same mechanism to recompute them after optimization.
