changes to adapt to compressed line table format

[vtjnash]

This contains some of the updates needed to keep working with the optimized debuginfo format (https://github.com/JuliaLang/julia/pull/52415). This is a draft, since someone needs integrate this to maintain support for old versions, where the old code is mostly marked here with my initials (jwn) and my initials should be removed entirely and instead the implementation in those places fixed.

It looks like this "optimization" introduces a very bad interaction with the new lineinfo format: https://github.com/JuliaDebug/JuliaInterpreter.jl/blob/28dd37ce0f7bcb357bfb820b1d6b53b98aa3796c/src/optimize.jl#L76-L92

julia> using JuliaInterpreter

julia> fnone1() = nothing;

julia> let m = only(methods(fnone1))
           JuliaInterpreter.FrameCode(m, JuliaInterpreter.get_source(m); optimize=true).src.debuginfo
       end
Core.DebugInfo(Symbol("REPL[2]"), nothing, svec(), "\x01\0\0\0\0\0\0\0\0\0\0\0\x01\x01\0")

julia> fnone2() = nothing;

julia> let m = only(methods(fnone2))
           JuliaInterpreter.FrameCode(m, JuliaInterpreter.get_source(m); optimize=true).src.debuginfo
       end
Core.DebugInfo(Symbol("REPL[4]"), nothing, svec(), "")

This PR is obviously not finished yet, but I want to push ahead with it as is to avoid holding up progress on other packages in the ecosystem. We can tackle the specific issues that I've identified so far later on (likely when Jameson returns).
