Breakpoints on JITted code

[Edd Barrett <edd@theunixzoo.co.uk>]

Hi,

I've recently implemented a simple gdb plugin [0] for a JIT I'm working on.

Lineinfo is working well, but I was expecting to be able to set breakpoints on
the names of JITted code functions (where the name is the one passed to the
`name` argument of block_open()), but this doesn't appear to be the case. gdb
allows me to set a pending breakpoint, but doesn't stop when a JITted function
of that name is reached.

Should I be able to set breakpoints by name for JITted code functions?

I'm using gdb-13.1 on Debian/amd64. I tried with gdb-14.2, but something about
my plugin causes gdb to crash with:
```
internal-error: sect_index_text not initialized".
```

Applying this patch [1] doesn't make that go away:

Cheers
