[PATCH] Fix transparent alias chain construction in change_decl_assembler_name

[Ilya Enkovich]

Hi,

Here is a small patch to fix ICE in change_decl_assembler_name.  I found this 
problem working on my experimental branch which uses transparent alias chains 
heavily and I don't have reproducer for the trunk.

Bootstrapped and checked on linux-x86_64.

Thanks,
Ilya
