Seen when cross-building GCC for ARM targets too.

The problem appeared with r223252:
2015-05-16  Jan HUbicka  <hubicka@ucw.cz>

        * tree.c (verify_type_variant): Verify tree_base and type_common flags.
        (verify_type): Verify STRING_FLAG.

--- Comment #6 from Jan Hubicka <hubicka at gcc dot gnu.org> ---
I suppose the problem here is that stor-layout adds TYPE_NO_FORCE_BLK on the
main variant.
I suppose either we can copy it consistently:
Index: stor-layout.c
===================================================================
--- stor-layout.c       (revision 222869)
+++ stor-layout.c       (working copy)
@@ -1834,6 +1834,7 @@
          TYPE_ALIGN (variant) = valign;
          TYPE_PRECISION (variant) = precision;
          SET_TYPE_MODE (variant, mode);
+         TYPE_NO_FORCE_BLK (variant) = TYPE_NO_FORCE_BLK (type);
        }
     }
 }

or declare the flag to be local to stor-layout, clear it in free_lang_data and
avoid its LTO streaming.

When building an SH cross compiler, there is a similar error when building
libstdc++.  The patch in comment 6 makes the build run to completion.

Jan, when do you plan to commit your patch?

So far it made it impossible for me to run validations on a subset of 29
commits related to ARM/AArch64 targets since the ICE was introduced.

This problem is also seen in the the sparcv9-*-linux-gnu and
sparc64-*-linux-gnu builds.  Both builds pass that point after applying the
patch in #6, but then they break for what is apparently another problem.

--- Comment #11 from Andreas Tobler <andreast at gcc dot gnu.org> ---
For the record from my side:

sparc-solaris and arm*-*-freebsd* are also affected. Applying the line from #6
cures the bootstrap on arm. But sparc-solaris is still broken, 66252 is the
pointer there.
