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
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.

For PR723:
- Provide for the include of ENABLE_ASSERTIONS flag from the configuration.
- Enhance the documentation for ENABLE_OPTIMIZED

For PR723:
Print out something at the end of the build that indicates what kind of
build has just completed.

Ignore stuff built by "make dist".

A saner workaround. I hope.

Temporary workaround for a Mac OSX specific issue.

Added more shuffle tests

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@27481 91177308-0d34-0410-b5e6-96231b3b80d8

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.
