Added the capability for the test driver to split the sys.stderr/sys.stdout into 

different configuration-based files using the config file.  For example:

    sys.stderr = open("/tmp/lldbtest-stderr", "w")
    sys.stdout = open("/tmp/lldbtest-stdout", "w")
    compilers = ["gcc", "llvm-gcc"]
    archs = ["x86_64", "i386"]
    split_stderr = True # This will split the stderr into configuration-specific file
    split_stdout = True # This will split the stdout into configuration-specific file

will produce:

/tmp/lldbtest-stderr
/tmp/lldbtest-stderr.arch=i386-compiler=gcc
/tmp/lldbtest-stderr.arch=i386-compiler=llvm-gcc
/tmp/lldbtest-stderr.arch=x86_64-compiler=gcc
/tmp/lldbtest-stderr.arch=x86_64-compiler=llvm-gcc
/tmp/lldbtest-stdout
/tmp/lldbtest-stdout.arch=i386-compiler=gcc
/tmp/lldbtest-stdout.arch=i386-compiler=llvm-gcc
/tmp/lldbtest-stdout.arch=x86_64-compiler=gcc
/tmp/lldbtest-stdout.arch=x86_64-compiler=llvm-gcc

as a result of splitting stderr and stdout.  In addition, each configuration can have
its individual top level relocated directory to house the test files as well as the
intermediate files by using '-r dir' to relocate the tests into a new relocated directory
instead of running the tests in place.
