Support accessing static trait members and methods from outside

[roberthusak]

Test case:

<?php
trait T {
  public static function foo() {
    echo "foo";
  }
  public static $bar = "bar";
}
T::foo();
echo T::$bar;

Expected result: foobar

Actual result: Unhandled Exception: System.BadImageFormatException: An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B) - this is probably caused by the unfilled type parameter T0, because T::foo() is compiled as T<T0>.foo(ctx)

Nice test case, I wouldn't ever believe PHP allows using members of a trait directly.

Yes, implicit type parameter TSelf is not specified.

Thanks, well, I was surprised, too..

more or less fixed in recent commits, still not handled in runtime binders
