TwoAddressInstructionPass doesn't really require LiveVariables, it just needs to update it if it's already around.

Also, move large sets and vectors out of instance variables and onto the stack,
and give them more reasonable sizes.

to be passed the list of value types, and use this
where appropriate.  Inappropriate places are where
the value type list is already known and may be
long, in which case the existing method is more
efficient.

Add a version of AsmPrinter::EOL that takes a const char* so that we don't have to do as many implicit std::string constructions.
Unfortunately, this doesn't appear to translate to a real speedup in practice.

This fixes PR2503, though we should also fix other passes not to emit this kind of code.
