Improve error handling for invalid breakpoint `-t` and `-x` options.
Breakpoint option `-t` checks that `option_arg` is empty by checking `option_arg[0] == '\0'`. This is unnecessary: the next two checks for comparing against "current" and calling `getAsInteger` already gracefully handle an empty StringRef. If the `option_arg` string is empty, this crashes (or triggers an assertion failure with asserts enabled). Also, this sets the thread id to `LLDB_INVALID_THREAD_ID` if the thread id is invalid -- it should just not set the thread id.
Likewise of `-x` which checks `option_arg[0] == '\n'` unnecessarily.
I believe both of these bugs are unreachable via normal LLDB usage, and are only accessible via the fuzzer -- most likely some other CLI parsing is trimming whitespace and rejecting empty inputs. Still, it doesn't hurt to simplify this bit.
