[PATCH v6 8/10] selftest: Add script to compile & run userspace test program

[Daniel Santos]

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"
payload		0
use_leftmost	0
use_rightmost	0
use_count	0
unique_keys	0
insert_replaces	0
test_num	0

reps		0x20000
count		0x800
keymask		0xfff

logfile		runtest.log
datafile	runtest.out
