Now that PASS_INFO() exists, use it in the other existing gcc plugins,
instead of always open coding the same thing.
Based on updates to the grsecurity/PaX gcc plugins.

Add a very simple plugin to demonstrate the GCC plugin infrastructure. This GCC
plugin computes the cyclomatic complexity of each function.
The complexity M of a function's control flow graph is defined as:
M = E - N + 2P
where
E = the number of edges
N = the number of nodes
P = the number of connected components (exit nodes).
