While operating on a breakpoints, is it correct to use 'breakpoint delete' without
previous 'breakpoint disable'? With this scenario, I'm observing 6.0.0-rc2 crash with:
$ /home/dantipov/.local/llvm-6.0.0/bin/lldb t-thread2

About to delete all breakpoints, do you want to do that?: [Y/n] Y
All breakpoints removed. (1 breakpoint)

Segmentation fault (core dumped)
There is no crash if 'breakpoint disable' was issued before 'breakpoint delete'.
