Subject: [PATCH v5 22/25] selftest: Add script to compile & run userspace test program

This is a basic script is designed to automate the testing process (for
a single compiler) and generate delimited text output suitable for later
processing. All test parameters can be supplied via the environment, or
defaults will be used for them. The following variables affect the
script and if not supplied, will have the these default values:

CC="gcc"
KERNELDIR="../../../../.."
CFLAGS="-O2 -pipe -march=k8"
key_type="u64"
use_leftmost=0
use_rightmost=0
use_count=0
unique_keys=0
insert_replaces=0
augmented=0
test_num=0

Other variables are hard-coded and will have be tweaked to need.
