1c4d0a214a Correct the computation of when to add the padding. It is not based on the
member's size. It is based on the oddness/evenness of the file pointer.
This fixes a bug with llvm-ar not being able to read archives produced by
llvm-ranlib when there are members with odd long file name lengths.

640ab4f4f6 Don't save an iterator, just use post-increment.

a181a37bb4 Make findModulesDefiningSymbols modify its symbols argument so we can \
eliminate symbols defined by the archive efficiently

a98ccac6fc Fix some things for Mac OSX archives:
* ensure trailing spaces are eliminated so they don't factor into the
  length of a member's name.
* make sure all the bytes of a name are written even if the name ends in
  multiple null characters (bug in OSX ar)
* make sure we provide the full member name when searching for symbols so
  the module name is not accidentally duplicated.

3e245bd4d5 Make sure we parse bytecode with a module identifier that reflects the full
name of the module: "Archive.a(object.o)"

f59013e0fa Despite documentation to the contrary, Mac OSX and BSD 4.4 archive formats
*do* include the length of the long file in the length of the member and
they are *not* null terminated.

52da956231 * Make sure the string table gets read even if there isn't a foreign
symbol table.
* Make sure we update the file pointer for each member when rebuilding the
  symbol table.

yet supported but writing works. Way too early to review this. More to come
