PPL: Remove support for PPL and CLooG/PPL
Now that versions of gcc that required PPL are no longer supported
( >= gcc-4.5.x AND <= gcc-4.7.x )
...we no longer require PPL or CLooG/PPL.
This commit:
* Removes PPL
* Removes CLooG/PPL
* Updates the documentation
* Updates build script for CLooG and GCC
* Removes PPL and CLooG/PPL from scripts/addToolVersion.sh and
scripts/showSamples.sh
* Adds ISL to scripts/addToolVersion.sh and scripts/showSamples.sh
I know that sounds like a lot for one commit, but it was all kind of
inter-tangled.
