Make lldb::Regex use StringRef.

This updates getters and setters to use StringRef instead of
const char *.  I tested the build on Linux, Windows, and OSX
and saw no build or test failures.  I cannot test any BSD
or Android variants, however I expect the required changes
to be minimal or non-existant.
