[Bug rtl-optimization/15473] Sibcall optimization for libcalls.

This is not a tree-ssa problem, we don't even know about libcalls 
at the tree level (that's the whole point! or at least, one of them). 
If anything, this is an rtl optimization problem. 
 
This also is not code pessimization, just lack of an optimization. 
Please use that keyword when we _pessimize_ your code (ie "make it 
worse than without optimization"). 
 
You might be able to fix this when the tree profiling branch is 
merged.  At that point you'd have the CFG, and perhaps (but I'm 
not sure) you can teach calls.c to build the libcall as a sibcall.
