Hi.  I removed 17821, 17799, 17798 and 17681.
I'm just not going to get time to finish them right now.
They weren't super important though.

OTOH, I just found a bug that I'd like to make a blocker for 7.9.

I'm adding support for Two Level Linetables:

and when I run gdb on programs compiled with this support
gdb goes into an infinite loop. :-(

There are actually two bugs here:
17890: gdb needs to punt when it sees a dwarf line table header
version it doesn't understand
17891: how is SIGFPE handling supposed to work?  currently gdb goes
into an infinite loop

I don't have a strong opinion on getting 17891 fixed for 7.9,
but I would like 7.9 to not hang when given tll-enabled binaries.
The fix is safe and easy enough.
