Pass1 statically binds constants at compile time in namespace

[bwoebi]

Description

The following trivial variation of test ext/opcache/tests/bug66251.phpt, ran with opcache:

<?php
namespace X;
printf ("A=%s\n", getA());
const A="hello";
function getA() {return A;}

Resulted in this output:

A=hello

But I expected this output instead:

Fatal error: Uncaught Error: Undefined constant "X\A" in %s:5
Stack trace:
#0 %s(2): X\getA()
#1 {main}
  thrown in %s on line 5

Apparently c2c78dc has changed it from checking from generic DO_FCALL to only ICALL, which made this test pass, but only in the specific tested scenario.
