gcc:
* Makefile.in: Remove all references to s-under and underscore.c.
* collect2.c, tlink.c: Change all uses of prepends_underscore
to look directly at USER_LABEL_PREFIX.
gcc/cp:
* Make-lang.in: Build cp/cxxfilt.o from $(srcdir)/cp/cxxfilt.c,
and c++filt from cxxfilt.o + version.o + $(LIBDEPS).
* cxxfilt.c: New file: split from libiberty/cplus-dem.c, with
minor adjustments (use version_string, eliminate yet another
duplicate of xmalloc)
libiberty:
* cplus-dem.c: Code code under #ifdef MAIN moved to gcc/cp/cxxfilt.c.
* testsuite/Makefile.in: Adjust for test-demangle.
* testsuite/regress-demangle: Deleted.
* testsuite/test-demangle.c: New file.
* testsuite/demangle-expected: Change \$ to $ throughout, now that
this file is not being read by a shell script.
