- Fix a really nasty bug in the bytecode reader that caused it to fail
...
reading bytecode files with > 255 types in them, but only when optimization
is enabled. This was caused by GCC shrinking an enum to a single byte
instead of a whole word.

- Make sure to only keep track of mappings that the TD pass may need in the

future. This prevents having spurious map entries to nodes that we really
don't care about. This allows us to reenable the DeadNodeElim, which was
disabled.
