This increases the readablity. This also adds some comments that explain
what this function does.

52277852a4 RegisterPass: Disable Polly by default 
We disable Polly by default and add a new option '-polly' that enables Polly.
This allows us to create an the alias

$ alias clang clang -Xclang -load -Xclang LLVMPolly.so

which loads Polly always into clang. It can now be enabled by running:

$ clang -O3 -mllvm -polly file.c

To enable it by default an alias pollycc can be create

$ alias pollycc clang -O3 -mllvm -polly

626227462d JSONImporter: Fix parameter ids when importing new access functions

We copy the ids now from the old parameter dimensions. This fixes the
problem.

only allow signed comparisons. Also, the new validator is only used to verify
loop bounds. Memory accesses are still handled by the old validator.

792509b0db 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. ;-)

This was simplified to using the isl_pw_aff representation of the affine
expressions and using the relevant isl functions to compare them.

d5a7bfc51d 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.
