Fix tests that fail in C++2a mode

The GNU extension that allows using the wrong allocator type with a
container is disabled for C++2a mode, because the standard now requires
a diagnostic. Fix the tests that fail when -std=gnu++2a is used.

Also remove some reundant tests that are duplicates of another test
except for a target specifier of c++11. Those tests previously set
-std=gnu++11 explicitly but that was replaced globally with a target
specifier. These tests existed to verify that explicit instantiation
worked for both C++98 and C++11 modes, but now do nothing because both
copies of the test use -std=gnu++14 by default. Instead of duplicating
the test we should be regularly running the whole testsuite with
different -std options.
