In an IPA pass, for each CFG node, I have a tree decl member from
which I can access the return type, name of the function, argument
names and its types, but I can't seem to find a way to get the
function code. I would guess it would be a basic block list but I
don't know where I can get it.

You need to get at the function structure from the cgraph node with DECL_STRUCT_FUNCTION (cgraph_node->decl). Then you can use one of the CFG accessors like basic_block_info_for_function().
