The code in `extract_mcdc_mappings` that allocates these bytes already knows how many are needed in total, so there's no need to immediately recompute that value in the calling function.

…idtwco coverage: Further simplify extraction of mapping info from MIR This is another round of rearrangement and simplification that builds on top of the changes made to mapping-extraction by rust-lang#124603. The overall theme is to take the computation of `bcb_has_mappings` and `test_vector_bitmap_bytes` out of the main body of `generate_coverage_spans`, which then lets us perform a few other small changes that had previously been held up by the need to work around those computations.
