2c70581338 Fix T_NUM_STRING negation 
T_NUM_STRING follows the rules of symtable numeric string
conversion. If the offset isn't an integer under those rules, it
is treated as a string. This should apply to negated T_NUM_STRINGs
as well.

8754b191f7 Fix "already in use" check inconsistencies/bugs 
This fixes the following issues:
 * "use function" and "use const" inside namespaced code were checking
   for conflicts against class imports. Now they always check against
   the correct symbol type.
 * Symbol conflicts are now always checked within a single file only.
   Previously class uses inside namespaced code were checked globally.
   This behavior is illegal because symbols from other files are not
   visible if opcache is used, resulting in behavioral discrepancies.
   Additionally this made the presence/absence of symbol errors dependent
   on autoloading order, which is volatile.
 * The "single file" restriction is now enforced by collecting defined
   symbols inside a separate hash table. Previously it was enforced
   (for the non-namespaced case) by comparing the filename of the
   symbol declaration. However this is inaccurate if the same filename
   is used multiple times, such as may happen if eval() is used.
 * Additionally the previous approach relies on symbols being registered
   at compile-time, which is not the case for late-bound classes, which
   makes the behavior dependent on class declaration order, as well as
   opcache (which may cause delayed early-binding).
 * Lastly, conflicts are now consistently checked for conditionally
   defined symbols. Previously only declaration-after-use conflicts were
   checked in this case. Now use-after-declaration conflicts are
   detected as well.

7abfaac901 Merge zend_execute_data->called_scope into zend_execute_data->This. 
"called_scope" made sense only for static method calls, for dynamic calls it was always equal to the class of $this.
Now EG(This) may store IS_OBJECT + $this or IS_UNUSED + "called_scope" (of course, "called_scope" may be NULL).
Some code might need to be adopted to support this change.
Checks (Z_OBJ(EX(This))) might need to be converted into (Z_TYPE(EX(This)) == IS_OBJECT).

This means we no longer allocate an unused VAR for the retval of
instructions that support unused results.

Nearly all instructions already used the result variable only if
it was used. The only exception to this was the return value
variable for internal function call results. I've adjusted the code
to use a stack zval for the unused return case now. As we have
retval specialization now, we know that it doesn't matter.

65e456f364 Introduce BIND_LEXICAL 
This opcodes inserts a local CV into the closure static variable
table. This replaces the previous mechanism of having static
variables marked as LEXICAL, which perform a symtable lookup
during copying.

This means a) functions which contain closures no longer have to
rebuild their symtable (better performance) and b) we can now track
used variables in SSA.

Now this is not possible. And extensions have to use zend_function.op_array.reserved[] for user functions and zend_function.internal_function.reserved[] for internal.

This was generated for a return from a try block with both a catch

because it either didn't exist in the first place or was explicitly
discarded using DISCARD_EXCEPTION.

0381c1b79e Fixed bug #69388 
Renamed compiler_context to oparray_context. Introduced per-file
file_context. Moved import tables into the file_context.

context_stack no longer exists, instead keeping backups of contexts
on C stack. Same for file contexts.

TODO: Move more things out of CG into file_context. There should be
a number of other things that we should not try to reuse in nested
compilations.

    Change "foreach" statement behavior (this is just a PoC yet)

    - "foreach by value" don't relay on internal array/object pointer and doesnt perform array duplication. It just locks it incrementing reference counter. If the original array is modified by some code, the copy on write is performed and "foreach" still work with the old copy.

    - it makes no difference if array given to "foreach by value" is reference itself

    - "foreach by reference" still use internal array/object pointer and should work similar to PHP-5. (This id not completely implemented)

14e29f5146 Reduced size of zend_op on 64-bit systems. 
the main idea - the smaller the zend_op structure, the lees memory traffic is required to load VM instructions during execution. The patch reduces the size of each opcode from 48 to 32 bytes (saves 16 bytes for each opcode, and applications use thousands of opoceds). This reduced the number of CPU cache misses by 12% and improved performance of real-life apps by 1-2%.

The patch affects how constants and jump targets are represented in VM during execution. Previously they were implemented as absolute 64-bit pointers. Now they are relative 32-bit offsets.

In run-time constant now should be accessed as:
  RT_CONSTANT(op_array, opine->op1) instead of opline->op1.zv
  EX_CONSTANT(opline->op1) instead of opline->op1.zv

Jump targets:
  OP_JMP_ADDR(opline, opline->op2) instead of opline->op2.jmp_addr

The patch doesn't change zend_op representation for 32-bit systems. They still use absolute addresses. The compile-time representation is also kept the same.
