[Task] Move SPU LLVM Pattern Matching to SPU Analyzer

[elad335]

SPU Analyzer allows us to detect properly patterns that resideover multiple blocks of SPU code. This is a relatively common practice in SPU code because at the time, it was beneficial for the SPU to execute code that interleaves mixed registers and code use to allow a single SPU to execute multiple instructions while fetching code memory at the same time for performance.
