I wonder whether you could put it directly on gerrit. Requires 
a couple of minutes to set up, but would put it in the right
pipe already.

It's also good timing. With 2.6 being finally branched, master
is open for fancy new features again.

The missing STL formatter would be no show stopper for the initial
version. And I don't even think there is a real problem at all as
the new Target/Profile/WhateverNameThatThingWillGet system allows
(among others) associating compilers with debuggers. So you can
have two Targets/Profiles/WhateverNameTheseThingsWillGet, one with
compiler llvm-gcc and debugger gdb, and one with clang/lldb.

Everything seems to be ok so far.
