RFA: revert libstdc++ r205810: simulator workload increase caused regression

[Hans-Peter Nilsson]

>From the revision range 205803:205810 (excluding:including) an
on, my autotester for cris-elf reports a regression:

Running /tmp/hpautotest-gcc1/gcc/libstdc++-v3/testsuite/libstdc++-dg/conformance.exp ...
WARNING: program timed out.
FAIL: 20_util/hash/chi2_quality.cc execution test

This appears to have come from revision r205810.  I can't find
the discussion or approval leading to that commit.  It seems
likely to have been a mistake, perhaps a commit intended for a
local repository.  Why else increase the workload, without
discussion with other target maintainers known to risk being
affected by this change?  The somewhat obvious fix is to just
revert revision r205810.

Ok to commit?

libstdc++:
	* testsuite/20_util/hash/chi2_quality.cc: Revert previous change.
