	Revert
	2014-03-04  Paulo Matos  <paulo@matos-sorge.com>

        * tree-streamer.c (record_common_node): Assert we don't record
        nodes with type double.
        (preload_common_node): Skip type double, complex double and
        double pointer since it is now frontend dependent due to
        fshort-double option.

        * gcc.dg/lto/pr55113_0.c: New testcase.
