ebbc95da49 Patch 10 for long double. Doing constants right needs expanding ConstantFP
to handle values bigger than double.  If we assume host==target and host
long double works correctly, this is not too bad, but we don't want to
have that limitation longterm.  I could implement accepting double
constants as long double or something like that, which would lead to
incorrect codegen with no errors; the more I think about that the worse
it seems.  Rather than do such a hack that would be backed out later,
I'm settling for giving reasonable error messages, for now.

a9bb713130 Make a preemptive bitcode format change to support PR1146. This lets us do
pr1146 in llvm 2.1 without ugly code to emulate old behavior.  This should
be merged into the 2.0 release branch.

ff294a4e1e add a char6 abbrev for bbnames and value names. This represents each character

e17b658c79 Implement support for globally associating abbrevs with block IDs, which
relieves us from having to emit the abbrevs into each instance of the block.
This shrinks kc.bit from 3368K to 3333K, but will be a more significant win
once instructions are abbreviated.
