23c33b1483 Optimized strings concatenation.
ZEND_ADD_STRING/VAR/CHAR are replaced with ZEND_ROPE_INTI, ZEND_ROPE_ADD, ZEND_ROPE_END.
Instead of reallocation and copying string on each ZEND_ADD_STRING/VAR/CAHR, collect all the strings and then allocate and construct the resulting string once.

commit 4638f7b914
Author: Dmitry Stogov <dmitry@zend.com>
Date:   Wed Jan 28 07:43:28 2015 +0300

    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)

b7715c7e8a Refactored parameter passing mechanism.
In PHP-5.6 and below each argument passed to user function was copies on VM stack twice.
Now we always have ZEND_INIT_FCALL (or simular) opcode that pushes "call frame" on top of VM stack.
"Call frame" is actually the same zend_execute_data structure.
All the following ZEND_SEND instructions push arguments on top of the stack in a way that they directly comes into corresponding CV variables of the called frame. Extra arguments are copied at the end of stack frame (after all CV and TMP variables) on function enterance.

There are two minor incompatibilities:
1) It's not allowed to decalre functions redefining arguments e.g. "function foo($a,$a) {}".
2) func_get_arg() and func_get args() return the current value of argument and not the original value that was sent.

Added opcode, still doing multiply instead of pow()

Yanked code from pow() implementation.

Should not handle negative long as exponent ourselves

Added test cases from pow()

Moved precedence higher than '~'

Added GMP operator overloading

Added ZEND_ASSIGN_POW (**=) operator.

Added pow() as a language construct.

Adjusted test cases for changed precedence.

Reduced pow() to shell function around ZEND_API pow_function()

Reduced test case to only contain edge cases
Added overloading test case

Moved unary minus above T_POW

Revert "Added pow() as a language construct."

Bad bad bad idea.

This reverts commit f60b98cf7a8371233d800a6faa286ddba4432d02.

Reverted unary minus behaviour due to previous revert.
Convert arrays to int(0)
Exponent with array as a base becomes int(0)
