Bug description:  array_count_values still mishandles numeric strings

Description:
------------
It seems this bug (with leading whitespace or a sign) was first introduced
in PHP 5.0.2, when Bugs #28435 and #29808 were fixed and it wasn't fixed
with Bug #34723. This function was never fixed the same way as other
functions (array_flip, array_key_exists) that also had the numeric string
problem as a result of internal function changes in PHP 5. I think
array_count_values is the only function that handles the values below
differently than "regular" array key/index syntax, array_combine,
array_flip, array_key_exists, etc.

Note: Everything was fine in 4.x; and I believe the examples *here* were
fine in 5.0 before 5.0.2 (though the above bugs existed).

The following patches against HEAD and 5.2 fix everything, including
previous bugs. (It's also around 40% faster with string values.)

mailing list (if you haven't already :-)), such as

Reproduce code:
---------------
$array = array('-000', ' 001', 1, ' 123', '+123');
var_dump(array_count_values($array));

Expected result:
----------------
array(5) {
  ["-000"]=>
  int(1)
  [" 001"]=>
  int(1)
  [1]=>
  int(1)
  [" 123"]=>
  int(1)
  ["+123"]=>
  int(1)
}

Actual result:
--------------
array(3) {
  [0]=>
  int(1)
  [1]=>
  int(2)
  [123]=>
  int(2)
}
