Register Polly passes automatically

Polly adds, after it is loaded into opt or clang, its passes to the default set
of -O3 passes. This means optimizing a program with clang and Polly becomes as
simple as executing.
clang -Xclang -load -Xclang lib/LLVMPolly.so -O3 program.c
The same should work for dragonegg powered gfortran, g++, ... or any other tool
that uses the PassManagerBuilder.
Warning: Even though using Polly became with this commit extremly easy, Polly
is still Pre-Alpha Quality. This means in most cases it will rather
destroy the world than doing anything positive. ;-)

ScopInfo: Do not return reference to member variable 'domain'.
...
Instead of returning a pointer to the domain, we return a new copy of it. This
is safer, as we do not give access to internal objects. It is also not
expensive, as isl will just increment a reference counter.
