969047749d Rename *.l files to *.re

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.

See also comments on
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.

db777e9199 Fix shifting signed values too far 
Signed shift of 31 for int and 63 for long is flagged as undefined
behavior by UBSan (-fsanitize=undefined) and seems to be indeed so
according to the standard.

The patch converts such cases to use unsigned.

then the class is not eligible for preloading.

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.

526344aa5e 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.

3269e88468 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.

b189c2432a Remove HAVE_STDARG_H 
The C89 standard and later defines the `<stdarg.h>` header as part of
the standard headers [1]. On current systems it is always present and
can be included unconditionally.

Checking for presence and functionality of the `<stdarg.h>` header and
variadic function is not relevant anymore on current systems since this
is always available.

Also Autoconf suggests relying on at least C89 or above [2] and [3].
