Remove unused Git attributes ident

The $Id$ keywords were used in Subversion where they can be substituted
with filename, last revision number change, last changed date, and last
user who changed it.

In Git this functionality is different and can be done with Git attribute
ident. These need to be defined manually for each file in the
.gitattributes file and are afterwards replaced with 40-character
hexadecimal blob object name which is based only on the particular file
contents.

This patch simplifies handling of $Id$ keywords by removing them since
they are not used anymore.

Improve performance of PowerPC64 ZEND_SIGNED_MULTIPLY_LONG

Detecting overflow with the XER is slow, partially because we have to
clear it before use. We can do better by using a trick where we compare
the high 64 bits of the result with the low 64 bits shifted right
63 bits.

This is 7% faster on a POWER8 running a simple testcase:

<?php
function testcase($count = 100000000) {
for ($i = 0; $i < $count; $i++) {
$x = 1;
$x = $x * 2;
$x = $x * 2;
$x = $x * 2;
$x = $x * 2;
}
}

testcase();
?>
