[LTO][PATCH] Fix multiple global variable definitions.

[=?big5?b?RG91ZyBLd2FuICjD9q62vHcp?= <dougkwan at google dot com>]

Hi,

    This patch fixes a thinko in a previous patch for the same
problem.  I checked for multiple definitions of globals with
initializers only.  This patch moves the logic to places in the
streams to handle all VAR_DECLs so we will not miss any.
