Support sample() in ByteCodeGenerator (but not the interpreter)
This doesn't implement sampling of child shaders (that's going to be
nearly impossible in the interpreter). But it does plumb the information
about sample calls to the byte code, so that SkVM can attempt to
translate those calls into evaluation of child shaders.
