Fixed bug #69896 'asm' operand has impossible constraints

Given it's an issue with 32-bit gcc-4.8, asm is disabled for the
breaking parts.

Improve performance of PowerPC64 fast_long_add_function

Detecting overflow with the XER is slow, partially because we have to
clear it before use.

PHP already has a fast way of detecting overflow in its fallback
c implementation. Overflow only occurs if the signs of the two
operands are the same and the sign of the result is different.
Furthermore, leaving it in c allows gcc to schedule the instructions
better.

This is 9% faster on a POWER8 running a simple testcase:

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

testcase();
?>

Improve performance of PowerPC64 fast_long_increment_function

Detecting overflow with the XER is slow, partially because we have to
clear it before use.

gcc does a better job of detecting overflow of an increment or decrement
than we can with inline assembly. It knows that an increment will only
overflow if it is one less than the overflow value. This means we end
up with a simple compare/branch. Furthermore, leaving it in c allows gcc
to schedule the instructions better.

This is 6% faster on a POWER8 running a simple testcase:

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

Make convert_to_* safe with rc>1

This only involves switching zval_dtor to zval_ptr_dtor for arrays
and making the convert_to_object for arrays a bit more generic.

All the other changes outside zend_operators.c just make use of
this new ability (use COPY instead of DUP).

What's still missing: Proper references handling. I've seen many
convert_to* calls that will break when a reference is used.

Also fixes bug #69788.
