Merge crt cc_objects

Currently there is a pattern of `crtbegin_${type}1` and `crtbegin_${type}` modules, where the former
has sources and the latter depends on the former. The two modules for a type share many properties,
rather than duplicating these, we merge modules, such that each type only has a `crtbegin_${type}`
module.
