be49d61b19 Remove old SVN keywords substitutions 
When the PHP source code was versioned in Subversion, there was
possible to substitute certain keywords such as $Id$ with revision
number, last change time and author name. Such approach is not used
in Git so this patch removes these outdated artifacts from source
code files.

    Improved SCDF<->SCCP interface

     - "get_feasible_successors" callback is changed into "mark_feasible_successors" and should mark necessary edges through scdf_mark_edge_feasible()
     - SCDF takes care about OP_DATA instruction
     - SCDF code is re-arranged to avoid repeatable checks

14023d39c1 Move builtin_ctzl portability into zend_bitset.h 
Use this function in both zend_mm_bitset_find_one and
zend_bitset_first.

Maybe zend_bitset.h is not quite the right place for it, but I did
not want to include this in a globally included header like
zend_long.h or zend_portability.h.

b1c3c9a525 Explicitly construct phi set during def propagation 
Previously the phi set was first computed during def propagation
and then computed again (per-block) during actual phi placement.
This commit changes this to store the phi set computed during
def propagation.

This makes SSA construction slightly faster (5%), but the main
purpose here is to pave the way for the next commit.

This also fixes a potential issue with the handling of irreducible
loops -- they generated additional phis, but these were not
accounted for in def propagation. (Though I'm not sure if we can
even have any irreducible loops right now.)
