Chris Lattner 963a97f1a3 Fix PR2369 by making scalarrepl more careful about promoting 
structures.  Its default threshold is to promote things that are
smaller than 128 bytes, which is sane.  However, it is not sane
to do this for things that turn into 128 *registers*.  Add a cap
on the number of registers introduced, defaulting to 128/4=32.

Chris Lattner ead0d88ad7 add a new -enable-value-prop flag for llcbeta, that enables propagation 
of value info (sign/zero ext info) from one MBB to another.  This doesn't
handle much right now because of two limitations:

1) only handles zext/sext, not random bit propagation (no assert exists 
   for this)
2) doesn't handle phis.

Chris Lattner e56d946a38 Fix the CBE's handling of instructions whose result is an i1. Previously, 
we did not truncate the value down to i1 with (x&1).  This caused a problem
when the computation of x was nontrivial, for example, "add i1 1, 1" would 
return 2 instead of 0.

This makes the testcase compile into:

...
  llvm_cbe_t = (((llvm_cbe_r == 0u) + (llvm_cbe_r == 0u))&1);
  llvm_cbe_u = (((unsigned int )(bool )llvm_cbe_t));
...

instead of:

...
  llvm_cbe_t = ((llvm_cbe_r == 0u) + (llvm_cbe_r == 0u));
  llvm_cbe_u = (((unsigned int )(bool )llvm_cbe_t));
...

This fixes a miscompilation of mediabench/adpcm/rawdaudio/rawdaudio and
403.gcc with the CBE, regressions from LLVM 2.2. Tanya, please pull 
this into the release branch.
