We forgot to include the unistd.h header file that defines the
functions mentioned above. This was not a problem with gnu C++ library,
however it did not work for libc++.

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

- Use uppercase letters according to the LLVM coding style
- Rename functions to not include 'tiledSchedule', but just Schedule. This
is more correct as tiling might be disabled.

The new isl_id support for parmeters created problems when importing new
access functions. Even though the parameters had the same names,
they were mapped to different ids and where therefore incompatible.
We copy the ids now from the old parameter dimensions. This fixes the
problem.

Parameters can be complex SCEV expressions, but they can also be single scalar
values. If a parameters is such a simple scalar value and the value is named,
use this name to name the isl parameter dimensions.

This does not work reliable and is probably not needed. I accidentally changed
this in this recent commit:

ScopDetect: Use INVALID macro to fail in case of aliasing
This simplifies the code and also makes the error message available to the
graphviz scop viewer.

address is part of the access function. Also remove unused special cases that
were necessery when the base address was still contained in the access function
llvm-svn: 144280
Previously we allowed in access functions only a single SCEVUnknown, which later
became the base address. We now use getPointerBase() to derive the base address
and all remaining unknowns are handled as parameters. This allows us to handle
cases like A[b+c];

This check was necessary because of the use AffineSCEVIterator in TempScopInfo.
As we removed this use recently it is not necessary any more.
