Whenever a tag has any TAL content, emit the new tagDict opcode with a

dict of the raw attribute values.  Also, put beginScope/endScope
around each tag for which a tagDict is emitted, rather than only for
tags using define or repeat.  This affects the generated code, but
doesn't affect semantics (according to the tests).
