Fix bug #46311: Pointer aliasing issue results in miscompile on gcc4.4

The code violated the strict aliasing restriction, because it
dereferenced the same pointer as zval** once and as void**
afterwards. Now both occurances dereference void** and cast to
zval* in the former case.
Merge branch 'PHP-5.5'
Remove duplicate calls to set filename & lineno for the DTRACE_FUNCTION_ENTRY/RETURN cases
Fix pgsql notice test failure
Fix intl build

Turns out that you can't use implicit void pointer casts if intl
is compiled.
Merge branch 'PHP-5.5'
Forgot newline in test
Remove trailing whitespace in test

Third try to make this work...
Apply pgsql notice test fixes to PHP-5.5
Merge branch 'PHP-5.5'
Fixed other compiler warnings
Merge branch 'PHP-5.4' into PHP-5.5

* PHP-5.4:
  Fixed other compiler warnings
Merge branch 'PHP-5.5'

* PHP-5.5:
  Fixed other compiler warnings
trivial fix spl_autoload_functions()
adapted the function args for ereg

And that actually seems to be it, all tests pass so far. So lets
see how it goes in the fture, too easy but seems to be done for now .
