08d67c7763 change AnnotationManager to use 'const char*' instead of std::string. this fixes the leakage of those strings and avoids the creation of such strings in static cosntructors (should result in a little improvement of startup time)

18fae69723 CellSPU: 
(a) Remove conditionally removed code in SelectXAddr. Basically, hope for the
    best that the A-form and D-form address predicates catch everything before
    the code decides to emit a X-form address.
(b) Expand vector store test cases to include the usual suspects.

3b48501adc Teach MatchScaledValue to handle Scales by 1 with MatchAddr (which 
can recursively match things) and scales by 0 by ignoring them.

whole huge app.

21d9003087 Initial support for anti-dependence breaking. Currently this code does not

make use of it to help with the post-pass scheduler.
