Teach CIndex's cursor visitor to restrict its traversal to a specific
region of interest (if provided). Implement clang_getCursor() in terms
of this traversal rather than using the Index library; the unified
cursor visitor is more complete, and will be The Way Forward.
Minor other tweaks needed to make this work:
- Extend Preprocessor::getLocForEndOfToken() to accept an offset
from the end, making it easy to move to the last character in the
token (rather than just past the end of the token).
- In Lexer::MeasureTokenLength(), the length of whitespace is zero.
