Remove simplifyConst cases on unequal types

A lot of the cases in simplifyConst are no longer relevant as our IR
arithmetic/bitop insts no longer take cells. We used to have IR like:

  Add(Null, StaticStr("123a"))

and we'd want to fold it, but now we have:

  AddInt(ConvCellToInt(Null), ConvStrToInt(StaticStr("123a")))

Move some container/collection stuff out

Very few translation units actually need the container
functions, compared to the number that include builtin-functions.h
somehow, so put them in their own header.  Also move getCollectionSize
out of ObjectData so we don't need to define
FAST_COLLECTION_SIZE_OFFSET from the complex-types.h cluster.

Remove the Opcode typedef

This turned out not so bad, probably in part because I mostly
just changed Opcode*'s to Op*'s without thinking about which ones
should've been PC.  The only hard part was I went down the wrong path
for Unit::offsetOf at first.
