Fix clients like this:

Browse Source 
delete ParseBytecodeFile(InputFilename, 0, &ErrorMessage);
  llvm_shutdown();
  delete ParseBytecodeFile(InputFilename, 0, &ErrorMessage);

The primitive type objects failed to ressurect themselves after shutdown, leading
to crashes in clients that used them after llvm_shutdown().

This solution isn't wonderful, because we clearly have static ctors.  However,
the code it replaces was just as bad, so it's not a regression.
