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.

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.

Support detection of a "CVS" directory at configure time to distinguish
whether this is a release build or a "from tree" build. This knowledge is
used to set the defaults for --enable-optimzied and --enable-assertions
options.

- Provide for the include of ENABLE_ASSERTIONS flag from the configuration.
- Enhance the documentation for ENABLE_OPTIMIZED

Print out something at the end of the build that indicates what kind of
build has just completed.

.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.

by the frontend to shuffles.

llvm-svn: 27475

- Normalize shuffle nodes so result vector lower half elements come from the
  first vector, the rest come from the second vector. (Except for the
  exceptions :-).
- Other minor fixes.

 vec_vperm(A, B, (vector unsigned char){14});

to:
        vspltb v0, v0, 14
