[committed] libstdc++: Remove dg-options "-std=c++98" from TR1 tests

[Jonathan Wakely <jwakely@redhat.com>]

Tested x86_64-linux. Pushed to trunk.

-- >8 --

These tests need slight adjustments to be valid in C++11 and later, but
there's no reason that can't be done, so that we test them in more
modes.

libstdc++-v3/ChangeLog:

	* testsuite/tr1/6_containers/utility/pair.cc: Remove dg-options
	and qualify ambiguous calls to get.
	* testsuite/tr1/8_c_compatibility/cmath/pow_cmath.cc: Adjust
	expected result for std::pow(float, int) as per DR 550.
