<pre>Example:
int f(const int &p) {
return p;
}
=>
int f_optimized(const int p) {
return p;
}
Idea: clone function to modify parameters(if external linkage; modify directly
if static one), modify callsites -> replace const references with copies if
sizeof(T) <= sizeof(T *).
Maybe a new opt pass or part of a current one (which one?) ?</pre>
