Err... There's a fantasticly better solution, which would solve
the *actual* problem, not something related to the problem. And
will probably solve not-yet-reported debugging problems on other
platforms as well.
Namely, in thread_prologue_epilogue_insns, after emitting the
prologue, move all of the line number notes after the prologue.
I'm not sure.
(1) It's a good thing to emit all the prologue insns the same way, either
all via RTL or all via asm code. So I think this is a valuable cleanup
anyway.
(2) Do we have any evidence that any other machine needs this? Why fix
a machine-specific problem in a mahine-independent way?
