For PR723:
Configure with the --enable-optimized and --enable-assertions option to
ensure that binary RPM packages are built with the options required by the
feature request.

For PR723:
1. Don't force debug builds to have assertion checking turned on always.
   Let the default (on) be taken, or overridden by the command line
2. Create two new BuildModes based on assertion checking: Release+Assert
   and Debug-Assert.
3. Ensure that when building a distribution we get a release build with
   assertions enabled, regardless of the tree's configuration.
4. (unrelated) Fix library name generation for llvm-config usage.

For PR723:
Support detection of a "CVS" directory at configure time to distinguish

used to set the defaults for --enable-optimzied and --enable-assertions

We have an assertion that checks that we do not encode null values into the
.bc file if they are supposed to be implicit.  This is cool, except that it
checked *after* constant expr folding: improving constant expr folding could
cause the .bc reader to assert out on old .bc files.  Move the check so that
it checks all simple constants, but no constantexprs.

Do not create ZEXTLOAD's unless we are before legalize or the operation is
legal.

New testcase

Ask legalize to promote all vector shuffles to be v16i8 instead of having to
handle all 4 PPC vector types.   This simplifies the matching code and allows
us to eliminate a bunch of patterns.  This also adds cases we were missing,
such as CodeGen/PowerPC/vec_splat.ll:splat_h.

* Add supprot for SCALAR_TO_VECTOR operations where the input needs to be
  promoted/expanded (e.g. SCALAR_TO_VECTOR from i8/i16 on PPC).
* Add support for targets to request that VECTOR_SHUFFLE nodes be promoted
  to a canonical type, for example, we only want v16i8 shuffles on PPC.
* Move isShuffleLegal out of TLI into Legalize.
* Teach isShuffleLegal to allow shuffles that need to be promoted.
