Detailed Description
This file defines the 'Statistic' class, which is designed to be an easy way to expose various metrics from passes. These statistics are printed at the end of a run (from llvm_shutdown), when the -stats command line option is passed on the command line.
This is useful for reporting information like the number of instructions simplified, optimized or removed by various transformations, like this:
static Statistic NumInstsKilled("gcse", "Number of instructions killed");
Later, in the code: ++NumInstsKilled;
NOTE: Statistics must be declared as global variables.
