8bd875f0de Do not allow bytecode files with unresolved references to be read. Doing
so lets wierd ConstantPlaceholder objects sneak into the system which
confuses it greatly.

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.

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.
