Makefile.in: Remove all references to s-under and underscore.c. 

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.

Note that, since HP's compiler generates object code straight from
C++ source, without going through an assembler, its mangled
identifiers can use all sorts of characters that no assembler would
tolerate, so the alphabet this function creates is a little odd.
Here are some sample mangled identifiers offered by HP:
typeid*__XT24AddressIndExpClassMember_
[Vftptr]key:__dt__32OrdinaryCompareIndExpClassMemberFv
__ct__Q2_9Elf64_Dyn18{unnamed.union.#1}Fv
This still seems really weird to me, since nowhere else in this
file is there anything to recognize curly brackets, parens, etc.
I've talked with Srikanth <srikanth@cup.hp.com>, and he assures me
this is right, but I still strongly suspect that there's a
misunderstanding here.
If we decide it's better for c++filt to use HP's assembler syntax
to scrape identifiers out of its input, here's the definition of
the symbol name syntax from the HP assembler manual:
Symbols are composed of uppercase and lowercase letters, decimal
digits, dollar symbol, period (.), ampersand (&), pound sign(#) and
underscore (_). A symbol can begin with a letter, digit underscore or
dollar sign. If a symbol begins with a digit, it must contain a
non-digit character.
