[committed] libstdc++: Fix some problems in PSTL tests

[Jonathan Wakely]

libstdc++-v3/ChangeLog:

	* testsuite/25_algorithms/pstl/alg_nonmodifying/find_end.cc:
	Increase dg-timeout-factor to 4. Fix -Wunused-parameter
	warnings. Replace bitwise AND with logical AND in loop
	condition.
	* testsuite/25_algorithms/pstl/alg_nonmodifying/search_n.cc:
	Replace bitwise AND with logical AND in loop condition.
	* testsuite/util/pstl/test_utils.h: Remove unused parameter
	names.

Tested x86_64-linux. Committed to trunk.
