Parse a relocation to a different user function out of the object file.

This updates to a newer inkwell to pick up a fix to Section::get_contents. Picking that up changed builder.build_struct_gep to return a Result, and there's many API updates scattered around to support that.

Compute the function names for all local and imported functions in the module in advance and pass that mapping to the function code generation.

debug_trap is added to Intrinsics, though all users are commented out.
