Rafael Espindola 594e676cbe llvm-ar: Pad the symbol table to 4 bytes.
It looks like ld64 requires it. With this we seem to be able to bootstrap using
llvm-ar+/usr/bin/true instead of ar+ranlib (currently on stage2).

Rafael Espindola c79bff6bb1 Basic support for BSD symbol tables in archives.
This could be optimized and for now we only produce __.SYMDEF
and not "__.SYMDEF SORTED".

Nick Kledzik f44dbda542 Object, support both mach-o archive t.o.c file names
For historical reasons archives on mach-o have two possible names for the 
file containing the table of contents for the archive: "__.SYMDEF SORTED" 
and "__.SYMDEF".  But the libObject archive reader only supported the former.

This patch fixes llvm::object::Archive to support both names.

Kevin Enderby 8da4bd60fb Changed the lvm-nm alias "-s" for -print-armap to "-M".
This will allow the "-s" flag to implemented in the future as it
is in darwin’s nm(1) to list symbols only in the specified section.

Given a LGTM by Shankar Easwaran who originally implemented
the support for lvm-nm’s -print-armap and archive map symbols.

Kevin Enderby 8c50dbb8cb Add support for BSD format Archive map symbols (aka the table of contents
from a __.SYMDEF or "__.SYMDEF SORTED" archive member).

Kevin Enderby 26646108c9 Fix some double printing of filenames for archives in llvm-nm when
the tool is given multiple files.  Also fix the same issue with Mach-O
universal files. And fix the newline spacing to separate the output
in these cases.

Kevin Enderby 6abc2e58ac Fix llvm-nm to print the full 64-bit address for symbols in 64-bit object files.
The implementation might be better to have a method is64Bit() in the class
SymbolicFile instead of having the static routine isSymbolList64Bit() in
llvm-nm.cpp .  But this is very much in the sprit of isObject() and
getNMTypeChar() in llvm-nm.cpp that has a series of if else statements
based on the specific class of the SymbolicFile.  I can update this if
folks would like.

Also the tests were updated to be explicit about checking the address for
64-bits or 32-bits from object files.

Rafael Espindola 0c8a3524b8 Add a minimal implementation of ranlib.
This is just enough to get "llvm-ranlib foo.a" working and tested. Making
llvm-ranlib a symbolic link to llvm-ar doesn't work so well with llvm's option
parsing, but ar's option parsing is mostly custom anyway.

This patch also removes the -X32_64 option. Looks like it was just added in
r10297 as part of implementing the current command line parsing. I can add it
back (with a test) if someone really has AIX portability problems without it.

Rafael Espindola b6b5f52ee8 Add support for the 's' operation to llvm-ar.
If no other operation is specified, 's' becomes an operation instead of an
modifier. The s operation just creates a symbol table. It is the same as
running ranlib.

We assume the archive was created by a sane ar (like llvm-ar or gnu ar) and
if the symbol table is present, then it is current. We use that to optimize
the most common case: a broken build system that thinks it has to run ranlib.

Rafael Espindola ce7f52db48 Add an initial implementation of archive symbol table generation.
The symbol table has forward references in the file. Instead of allocating
a temporary buffer or counting the size and then writing, this implementation
writes a dummy value first and patches it once the final value is known.

There is room for performance improvement. I will implement them as soon as I
get some other features (like a ranlib mode) in.
