[Bug optimization/14440] New: [tree-ssa] [regression] no sib calling with _Bool types

[pinskia at gcc dot gnu dot org]

Here is a regression from the mainline:
_Bool t();

_Bool f(int i)
{
 return t();
}

t should be sibcalled but is not because the return type of f is really still int for some 
reason by the front-end (both the C and C++ front-ends, you have to #define _Bool bool 
for the C++ front-end to work though).
