This fixes the fact that our pretty printers say ungrammatical things
like "std::vector with 1 elements"
* python/libstdcxx/v6/printers.py (num_elements): New function.
(StdMapPrinter.to_string, StdSetPrinter.to_string)
(StdDequePrinter.to_string, Tr1UnorderedSetPrinter.to_string)
(Tr1UnorderedMapPrinter.to_string): Use num_elements.
* testsuite/libstdc++-prettyprinters/cxx11.cc: Adjust expected results
to use singular noun when there is only one element.
* testsuite/libstdc++-prettyprinters/debug.cc: Likewise.
* testsuite/libstdc++-prettyprinters/debug_cxx11.cc: Likewise.
* testsuite/libstdc++-prettyprinters/simple.cc: Likewise.
* testsuite/libstdc++-prettyprinters/simple11.cc: Likewise.
* testsuite/libstdc++-prettyprinters/tr1.cc: Likewise.
Tested x86_64-linux, committed to trunk.

Author: Jonathan Wakely <jwak...@redhat.com>

Make printers use singular noun for a single element
