[PATCH] Flip LANG_HOOKS_REDUCE_BIT_FIELD_OPERATIONS default

[Paolo Bonzini]

As agreed during the 4.3 release cycle.  I think Richi approved it on 
IRC (he said to do this instead of removing the langhook immediately) , 
but anyway I won't apply it until Monday so people have the chance to 
scream.

C, C++, ObjC, Ada already default to true.  ObjC++ should, but doesn't. 
  The other languages probably don't care.

Bootstrapped/regtested i686-pc-linux-gnu, all languages except Ada for 
which there's no change anyway; no failure.
