Tobias Grosser 39913e3648 test: Switch to new atomic instructions 
This fixes the test with recent versions of LLVM that do not support
the old atomic instructions any more.

Tobias Grosser 4dca439cfc Register Passes: Use -polly-optimizer=(isl|pocc) to switch optimizers 
This replaces the old option -polly-use-pocc. Also call the passes uniformly
-polly-opt-pocc and -polly-opt-isl.

Tobias Grosser 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

Tobias Grosser 29ee0b14d5 Do not use getNameStr() anymore. 
Instead we switch to the recommended getName(). This fixes compilation with
recent versions of LLVM.

Tobias Grosser 1ae9a60426 ScheduleOptimizer: Some style changes 
- 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.

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

Tobias Grosser 8f99c167cd ScopInfo: Use names of simple parameters to name the isl parameter dimensions. 
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.

Tobias Grosser fff5adca2e ScopDetection: Do not verify Aliasing 
This does not work reliable and is probably not needed. I accidentally changed
this in this recent commit:

Tobias Grosser e5e171eadd Reuse the old BaseAddress checking in SCEVValidator to make sure that no base 
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

Tobias Grosser b8710b5952 ScopDetect: Use getPointerBase to get the base pointer 
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];

Tobias Grosser e4e2f7b16e TempScop: Rename SCEVAffFunc to IRAccess 
The SCEVAffFunc is now only used to express memory accesses. Give it a proper
name and rework the class such that this is obvious.

This also removes the construction of MayAliasSets that became invalid when
removing the use of SCEVAffFunc.
