Extract allowed styles from libiberty, so we don't have to worry about our help messages getting out of date. The function probably belongs in libiberty/cplus-dem.c but it can be here for a while to iron out bugs. PR 28581 * demanguse.c: New file. * demanguse.h: New file. * nm.c (usage): Break up output. Use display_demangler_styles. * objdump.c (usage): Use display_demangler_styles. * readelf.c (usage): Likewise. * Makefile.am: Add demanguse.c and demanguse.h. * Makefile.in: Regenerate. * po/POTFILESin: Regenerate.
