[PATCH] Improve tests for contents of <new> header

This test for the contents of the <new> header doesn't get run for
C++98 mode and doesn't include the C++14 and C++17 additions. I've
split the C++98-only test into a separate file, and added the new
parts so they're tested conditionally depending on how the test is
run.
* testsuite/18_support/headers/new/synopsis.cc: Add C++14 and C++17
declarations.
* testsuite/18_support/headers/new/synopsis_cxx98.cc: New test.
Tested powerpc64le-linux, committed to trunk.
