[PATCH 0/3] Fix regression: expression completer and scope operator (PR gdb/22584)

[Pedro Alves]

This patch series fixes PR gdb/22584, a regression in the expression
completer:

 "(gdb) p std::[TAB]" => "(gdb) p std::std::"

GDB got confused above, there's no such thing as "std::std::".

Patch #1 factors out some code duplicated throughout the codebase.

The new function patched by patch #1 is used by patch #2 (the actual fix) uses.

Patch #3 fixes something in the new completion testing support
routines that I noticed while writing the tests for patch #2.
