Description:
------------
It is possible to have the following errors : 

"Encoding declaration pragma must be the very first statement in the script"
And Then : 
"Namespace declaration statement has to be the very first statement in the script"


Is is also possible to have the following, in place of the first statement :
"strict_types declaration must be the very first statement in the script"

In fact, namespace declaration should happen in first in the script, but AFTER
encoding or strict_types declare calls. 



Expected result:
----------------
All C code is in Zend/zend_compile.c file.

Line 4498 for "Encoding declaration pragma "
Line 4505 for "strict_types declaration pragma "

line 5827 for "Namespace declaration statement "

I suggest the second error message is updated and mention the 'declare' (see patch)
