This changes allows us to compile the gem5 simulator with ag++. It was tested with ag++ v0.8, built Apr 18 2013. Most of the changes are preprocessor directives like #ifndef __puma which have been inserted into the gem5 code. Unfortunately, a python script and a SWIG input file have been patched, too. Additionally, the CMake file has been updated. A single call to "make" now invokes the ag++ (instead of the g++) compiler front end. The new CMake target "gem5-allclean" should be used to clean the current project when building FailGem5. In addition to cleaning the Fail build directory, it also invokes "scons -c" in the gem5 build directory; that is, gem5 is cleaned as well. Change-Id: I20a92f025f34f626b81e30f2c873baeba189f83b
