This pass is responsible for selecting generic machine instructions to target-specific instructions.
It relies on the InstructionSelector provided by the target. Selection is done by examining blocks in post-order, and instructions in reverse order.

getAnalysisUsage - This function should be overriden by passes that need analysis information to do their job.
If a pass specifies that it uses a particular analysis result to this function, it can then use the getAnalysis<AnalysisType>() function, below.
