Gordon Henriksen 55cbec317d More fleshing out of docs/Passes.html, plus some typo fixes and
improved wording in source files.

// This file defines two passes to print out a module. The PrintModulePass pass
// simply prints out the entire module when it is executed. The
// PrintFunctionPass class is designed to be pipelined with other
// FunctionPass's, and prints out the functions of the module as they are
// processed.
