Bug description:The 'asm goto' constructs are not supported by LLVM

Description:
------------
There is a few places with code like __asm__ goto. For example
Zend/zend_operators.h:532

```
	__asm__ goto(
		"decq (%0)\n\t"
		"jo  %l1\n"
		:
		: "r"(&op1->value)
		: "cc", "memory"
		: overflow);
	return;
```

Please avoid using asm goto as it not supported by LLVM.
