Yes thanks, down from 4m39s to 2.7 seconds, so very much
preferable!

(To the skeptics: the coverage intended with the test, is
IMHO reached with all non-simulator targets also running
this.  Nothing target-dependent here.)

Also in line with many other depth-level-cousin test-files
named value.cc.  Still many more others seem to be
candidates for such pruning, judging by the time it takes
for a 'RUNTESTFLAGS=--target_board=cris-sim\
conformance.exp=values.cc' to get to *that* values.cc.

Though, some -DSIMULATOR_TEST-adjusted files use dg-options,
others dg-additional-options.  It seems the difference is
that by using dg-options, you lose "-include bits/stdc++.h".
Likely not intended.  If so, should Someone fix that by
preapproval but regtested?
