gallivm: optimize 16bit->32bit gather path a bit LLVM can't really optimize anything which crosses scalar/vector boundaries, so help a bit with some particular gather operations when the width is expanded (only do it for 16->32bit expansion for now), by doing expansion after fetch. That is probably a better solution anyway even if llvm would recognize it, makes for cleaner IR... Reviewed-by: Jose Fonseca <jfonseca@vmware.com>
