Bug description:Declare Encoding Compile Check Wrong

Description:
------------
The current compile-time error check for declare(encoding="...") is
incorrect.

Declare is a parse-time only directive, which does not respect scope.
The current compile-time checks for the declare(encoding) directive only
check to see if it's the first opcode in the active oparray.

This is fine if the active oparray is a file, however if it is a
function odd behavior will be allowed. In the provided test script,
"Bye" would be interpreted using the UTF-8 encoding pragma, where "Hi"
would use the default.



Test script:
---------------
<?php

echo "Hi";

function foo() {
    declare(encoding="UTF-8");
}

echo "Bye";

Expected result:
----------------
Fatal error: Encoding declaration pragma must be the very first
statement in the script

Actual result:
--------------
HiBye
