8f97278c49 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.

78e12c73e5 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.

67c46c8d70 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.

0dea46fe67 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.

94bd315c3f If a function is external, do not output a FunctionBlock for the function 
AT ALL.  This saves 11 bytes per external function from the bytecode file,
and is also required to make GhostLinkage work.
