LiveVariables::HandlePhysRegDef private they use information that is
not in memory when LiveVariables finishes the analysis.

Also update the TwoAddressInstructionPass to not use this interface.

The first change (which is disabled) compactifies all of the function constant
pools into the global constant pool, in an attempt to reduce the amount of
duplication and overhead.  Unfortunately, as the comment indicates, this is
not yet a win, so it is disabled.

The second change sorts the typeid's so that those types that can be used
by instructions in the program appear earlier in the table than those that
cannot (such as structures and arrays).  This causes the instructions to
be able to use the dense encoding more often, saving about 5K on 254.gap.
This is only a .65% savings though, unfortunately. :(

Fix iterator invalidation problems which was causing -mstrip to miss some
entries, and read free'd memory.  This shrinks the symbol table of 254.gap
from 333 to 284 bytes!  :)

occurs when the symbol table for a module has been stripped, making all of the
function local symbols go away.

This saves 6728 bytes in the stripped bytecode file of 254.gap (which obviously
has 841 functions), which isn't a ton, but helps and was easy.

This should get hunked over to the Sparc backend, along with
MachineCodeForInstruction and a bunch of files in include/llvm/Codegen,
but those battles will have to wait for a later time.
