[GH #837] Add benchmark to test encoding slowdown
stress_stringsu.pir tests encoding via sprintf and concat.
The fixed version is only a bit slower then the old broken version.
13.666s (broken) vs 13.506s (fixed) vs 3.022s (without encoding).
So fixing the encoding representation as STRING* in SREG and consts 'U'
is a worthwile goal.

Log Message:
-----------
[GH #837] New comparison benchmark against stress_stringsu.pir
Bad news:
There is almost no measurable speed advantage from ascii strings to encoded
strings.
With the fix and without the fix, as sprintf handling slows down the test 4x
times.
So converting a SREG and const to encoded STRING* will not gain much
performance.
