This change is to add some missing details to the help text and command
guide:
- Added a note to the command guide that --debug-macro also dumps
.debug_macinfo.
- Added a note to the command guide that --debug-frame and --eh_frame
are aliases, and in cases where both sections are present one command
outputs both.
- Changed the wording in the help output for --ignore-case and --regex to
closer match the command guide.
