Description:
------------
If a WSDL file is unavailable when running SoapClient::__construct(), PHP 
indicates a fatal error to STDERR yet continues to process the script.  This 
causes erroneous errors to end up in logs and creates a lot of misdirection around 
whether or not we have legitimate problems.

It should continue to generate the SoapFault which contains approximately the same 
message, but should not indicate the fatal error.

Test script:
---------------
<?php
set_error_handler(function($a,$b,$c,$d) { throw new ErrorException($b,0,$a,$c,$d); }, -1);

try {
	new SoapClient('https://example.com/foo.bar');
}
catch (SoapFault $e) {
	echo "SoapFault\n";
}
catch (ErrorException $e) {
	echo "ErrorException\n";
}
catch (Exception $e) {
	echo "Exception\n";
}
echo "I survived\n";
register_shutdown_function(function() {
	echo 'Shutdown';
});

Expected result:
----------------
STDERR:
(nothing)

STDOUT:
SoapFault
I survived
Shutdown

Actual result:
--------------
STDERR:
PHP Fatal error:  SOAP-ERROR: Parsing WSDL: Couldn't load from 
'https://example.com/foo.bar' : failed to load external entity 
"https://example.com/foo.bar"
