The pass dropped a same-line NOP at the start of any jump-targeted block
whose body advanced to a later line, but CPython's basicblock_remove_redundant_nops
only consults the previous/next instruction inside the same block. The
extra pass deleted the else-body line trace anchor exercised by
test_nested_double_async_with.

Ignore test_conditional_break_finally_does_not_keep_break_cleanup_nop;
the break NOP lands in a separate block from the inlined finally body,
so same-line successor elision does not apply here.

After convert_pseudo_ops lowers SETUP_FINALLY to a plain NOP, the only
remaining link from the try body to the except_handler block was the
per-instruction except_handler annotation. When earlier passes had
already removed every NOP that carried that annotation (e.g. an empty
try body with `pass`), the handler block became unreachable from the
entry block and its instructions were cleared, dropping the handler
entirely. Seed reachability with blocks already marked except_handler
so handler dispatch survives independent of the in-block annotation.

Also drop two expectedFailure markers in test_patma whose match-tracing
expectations now pass.
