83bb3d2f4e The new bytecode format supports emitting strings a special case. This is 
intended to save size (and does on small programs), but on big programs it
actually increases the size of the program slightly.  The deal is that many
functions end up using the characters that the string contained, and the
characters are no longer in the global constant table, so they have to be
emitted in function specific constant pools.

This pessimization will be fixed in subsequent patches.

9e893e8a3d Version 1.2 now supports encoding strings as a special case, to avoid having 
to emit all of those sbyte constants.

07ad64231f Eliminate the isStringCompatible function, using ConstantArray::isString. 
It's not clear why the code was looking for signed chars < 0, but it can't
matter to the assembler anyway, so the check goes away.  This also fixes
compatibility with arrays of [us]byte that have constantexprs in them.

Also slightly restructure some code to be cleaner.

9b0a5ee5bb Add new ConstantArray::isString(), as the conditions for using getString() 
are complex enough to check that it should be a seperate method.

While I'm here, improve ConstantArray::getNullValue a bit, though the
FIXME is still quite valid.

8ce750145d The only clients of the slot calculator are now the asmwriter and bcwriter. 
Since this really only makes sense for these two, change hte instance variable
to reflect whether we are writing a bytecode file or not.  This makes it
reasonable to add bcwriter specific stuff to it as necessary.
