Description:
RR: Add statistics to optimizers
Updates the compiler optimizers to returns statistics about each pass
instead of a simple boolean. This could be used to analyze
the effectiveness of an individual optimizer, tune the compiler
for code size/ compile time trade offs, or predict the effectiveness
of future passes of an optimizer.
