Fix a really subtle and obnoxious memory bug that caused issues with an
llvm-gcc4 boostrap.  Whenever a node is deleted by the dag combiner, it
*must* be returned by the visit function, or the dag combiner will not
know that the node has been processed (and will, e.g., send it to the
target dag combine xforms).

Several Changes To Support Building llvm-config:
1. If Perl is not available, don't run Perl dependent targets.
2. Check in FinalLibDeps.txt for build environments that can't build it
   because there's no Perl processor.
3. Ensure that FinalLibDeps.txt depends on LibDeps.txt so it is
   automatically regenerated.
4. Support objdir != srcdir building.

Turn a VAND into a VECTOR_SHUFFLE is applicable.
DAG combiner can turn a VAND V, <-1, 0, -1, -1>, i.e. vector clear elements,

a zero vector.
