67b84e4548 Fixed uninitialized var warning
Causes build failure on release+zts azure build. I'm rewriting this
code to separate the if/else handling, because they don't really
have anything in common anyway...

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.

afec3a9208 Avoid early-binding on unresolved types
Fixes bug #76451, and more importantly lays necessary groundwork for
covariant/contravariant types. Bug #76451 is just an edge case, but
once covariance is introduced this will become a common problem instead.

d0a56f707f Fixed bug #71030
Make sure to always fetch the RHS of a list assignment first, instead
of special casing known self-assignments, which will not detect cases
using references correctly.

As a side-effect, it is no longer possible to do something like
byRef(list($x) = $y). This worked by accident previously, but only
if $y was a CV and the self-assignment case did not trigger.
However it shouldn't work for the same reason that byRef($x = $y)
doesn't. Conversely byRef(list(&$x) = $y) and byRef($x =& $y)
continue to be legal.

7f72d771e8 Revert "Switch to bison location tracking"
This reverts commit e528762c1c.

Dmitry reports that this has a non-trivial impact on parsing
overhead, especially on 32-bit systems. As we don't have a strong
need for this change right now, I'm reverting it.

e528762c1c.

e528762c1c Switch to bison location tracking
Locations for AST nodes are now tracked with the help of bison
location tracking. This is more accurate than what we currently do
and easier to extend with more information.

A zend_ast_loc structure is introduced, which is used for the location
stack. Currently it only holds the start lineno, but can be extended
to also hold end lineno and offset/column information in the future.

All AST constructors now accept a zend_ast_loc* as first argument, and
will use it to determine their lineno. Previously this used either the
CG(zend_lineno), or the smallest AST lineno of child nodes.

On the parser side, the location structure for a whole rule can be
obtained using the &@$ character salad.

deb44d405e Revert "Detect invalid uses of parent:: during compilation"
This reverts commit a9e6667817.

Breakage found in the wild: Mockery uses a parent:: call in the
implementation regardless of whether the class has a parent or not:
4324afeaf9/library/Mockery/Mock.php (L600)

This change is not worth the compat break in 7.4.

b33fa18eab Remove unused PHP_AC_BROKEN_SPRINTF and AC_ZEND_BROKEN_SPRINTF
The sprintf function has been normalized to php_sprintf via
61364b5bb1.

This patch removes the checks to make a custom sprintf function

The ZEND_BROKEN_SPRINTF has been removed and the
hardcoded #define zend_sprintf sprintf is used.

The php_sprintf and zend_sprintf are now symbols to sprintf.

This patch now removes the custom PHP definitions of the php_sprintf and
zend_sprintf functions in favor of the C99 sprintf which is also
standardized in C89 already. Once, on some systems sprintf didn't behave
in same way.

While the compiler does not have the FBC set for zend_get_call_op, optimizer does, and so incorrectly results in ignoring these flags.
If someone has a better patch, please merge it ASAP, this appears to be correct as I and Nikita originally thought.

3cafa7f4df Assign (un)serialize_func during compilation
This avoids writing this cache at runtime, which is illegal if
preloading is used.

Not every serialize/unserialize function actually belongs to the
Serializable interface, but I think it's not a problem to assign
these anyway -- whether they are used ultimately depends on whether
Serializable is implemented.

Alternatively it might make sense to just drop these entirely. I
don't think this is performance critical functionality.

92ac598aab 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.
