   Depends what you consider serious (and what "backend" means).   
   There is bunch of compilers that use their own backend,   
   for example optimized Ocaml or SBCL Lisp.  If you aim at   
   highest possible speed, regardless of language, then they   
   can not compete.  If you look at native performance for   
   relevant languages, then they are top performers (there are   
   Lisp compilers which generate code via translation to C,   
   resulting speed is lower than obtained using SBCL).   
      
   Note that context was porting languages, "classic"   
   languages are covered by VSI, so relevant things are   
   backends for more exotic languages.  There was recent   
   trend to adopt LLVM in such cases, and Julia seem to   
   be prominent example of language dependent on LLVM.   
   But more popular approach seem to be via custom   
   backend or via C.  For example Haskell folks some time   
   ago said that LLVM does not really give them advantages   
   compared to going via C, and C way is easier.
