[Bug java/17488] New: Binary compatibility: must ensure static method's class remains live

["tromey at gcc dot gnu dot org" <gcc-bugzilla@gcc.gnu.org>]

At the moment, a reference to a static method won't cause the
method's class to be considered as live.  This can lead to
incorrect collection of the class.  The fix is to somehow
arrange for this class to be marked.

For static fields this is handled because we emit explicit
_Jv_InitClass calls for the field's class; the class reference
ends up in the constant pool and is marked there.

One potential fix would be to move class initialization calls
for static methods to the caller (they are now in the callee).
This might be difficult (there are many calls from C++, for instance).
