Clean up the documentation.
Simplify the file handling. It now only writes to std::cout. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14059 91177308-0d34-0410-b5e6-96231b3b80d8

// This tool provides analytical information about a bytecode file. It is

||||||
|
// intended as an aid to developers of bytecode reading and writing software. It
|
||||||
|
// produces on std::out a summary of the bytecode file that shows various
|
||||||
|
// statistics about the contents of the file. If the -details option is given
|
||||||
|
// then the output includes detailed information about each function in the
|
||||||
|
// bytecode file. The tool is also able to print a bytecode file in a straight
|
||||||
|
// forward text format // that shows the containment and relationships of the
|
||||||
|
// information in the bytecode file (-dump option).
