f5f1689ed2 Use a list instead of a vector to store intervals. This will be needed 
when we join intervals and one of the two will need to be removed.

0baa0af861 If these blocks are empty, there is no reason to even emit the bytecode blocks. 
This saves about 15K in 176.gcc, coupled with another patch that I'm working on.

7be08bfae1 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)

933619912b 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.

7969dc2bec 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.

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.

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.

8ce750145d The only clients of the slot calculator are now the asmwriter and bcwriter.

to reflect whether we are writing a bytecode file or not.  This makes it
reasonable to add bcwriter specific stuff to it as necessary.
