Diego Novillo b436bf3805 Add a new option --clean_build to validate_failures.py 
This is useful when you have two builds of the same compiler.  One with
your changes.  The other one, a clean build at the same revision.
Instead of using a manifest file, --clean_build will compare the
results it gather from the patched build against those it gathers from
the clean build.

Usage

$ cd /top/of/patched/gcc/bld
$ validate_failures.py --clean_build=clean/bld-gcc
Source directory: /usr/local/google/home/dnovillo/gcc/trunk
Build target:     x86_64-unknown-linux-gnu
