ba62115c2d The bcwriter does not want ConstantPointerRef's to be indexed, and the asmwriter never did!

44232deeda ConstantPointerRef's are no longer emitted. This saves 20028 bytes in the 
bytecode files when compiling 176.gcc, but more importantly will make it
easier to eliminate CPR's in the future (no new .bc revision will be
required to support them)

844284aabe Allow bytecode files to refer directly to global values as constants, instead 
of forcing them to go through ConstantPointerRef's.  This allows bytecode
files to mirror .ll files, allows more efficient encoding, and makes it easier
to eventually eliminate CPR's.

ed98fd7216 Change all of the bytecode reader primitives to throw exceptions instead of 
returning error codes.  Because they don't return an error code, they can
return the value read, which simplifies the code and makes the reader more
efficient (yaay!).

Also eliminate the special case code for little endian machines.

106bba1e9b 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.

to emit all of those sbyte constants.

691524bfbd 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.

599ab961c4 Add new ConstantArray::isString(), as the conditions for using getString()

7824ed3d12 Don't pass anything to the IntrinsicLowering class that is not_intrinsic, 
because that makes it abort. Also, fix a typo in a comment.

ENABLE_LLI tests on Shootout on zion, even if they all dump core" fund.

bcd7372d19 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.
