I would suggest to firstly look at clang-tidy. It is very simple to start
and it will make you more familiar with clang's AST
and you can also write some useful checks very fast.

With this configuration I compile llvm and clang with -j32 having only 16GB
of ram.
On 2 core machine it should not take more than 2h (usually arround 1h)
You should get *scan-build* binary. I am not sure if you need any other
binary than clang and scan-build
to run static analyzer
