strings: lower running time of TestCompareStrings
At each comparison, we're making a copy of the whole string.
Instead, use unsafe to share the string backing store with a []byte.
It reduces the test time from ~4sec to ~1sec on my machine
(darwin/amd64). Some builders were having much more trouble with this
test (>3min), it may help more there.
