here is a hopefully final version.
Ok by me. The dwarf edits look good too.

I re-tested my dwarf2 cfi propagation pass today, with the
partitioning vs eh edge splitting fix included. Only this
time I tested languages=all,ada,go instead of just =c,c++.
Lo and behold I find another latent problem, this time via
a Fortran test case.
The dwarf2 cfg pass is set to abort for
Well, technically it's not broken yet. It will be as soon as it starts
touching DF data, since this pass runs before pass_df_initialize_no_opt.
But the only real consumer of BB_PARTITION is pass_reorder_blocks. And
that pass is already gated to only run if optimization is enabled. So

Fixes an (intentional) .eh_frame size regression from

Without any actual shrink-wrapping, there are not many
