FunctionDecl should have 'initial' attribute

[davidmalcolm]

Before there is a CFG, the body of a function is in the function decl's DECL_INITIAL, as a block. This field should be exposed to Python.

This patch adds the attribute, but isn't complete; no tests or docs.

Actually, I am not sure this is correct. I think it should be DECL_SAVED_TREE instead, or perhaps in addition to. Apparently my knowledge of gcc is outdated :}

Sorry, I was really confused.

After gimplification you want access to the gimple body. So, I think there should be a way to access gimple_body(fndecl).

I just moved my pass to after the CFG is made, and that worked for me. I'm not sure of a specific case where it is useful to run earlier. So another option would be to WONTFIX this bug.
