[lldb] Start a new line for the next output if there are no symbols in the current symtab

[asmith]

Summary

If there is no newline the "lldb" prompt could be on the wrong line. To reproduce the missing newline you can do 'image dump smytab' on any binary.

Previously

Symtab, file = D:\upstream\build\Debug\bin\clang-diff.exe, num_symbols = 0(lldb)

Now

Symtab, file = D:\upstream\build\Debug\bin\clang-diff.exe, num_symbols = 0
(lldb)

Couple of options:

1. Can you give an example of before/after output?
2. Is the size_t change related?
3. Can you use -U999999 in the future when generating patches?
