[PATCH] Fix PR target/15546, IA64 bootstrap

[Andrew Pinski]

After fixing the rs6000 case of not marking a function as referenced,
I saw that IA64 was broken via a bug report, I tried and tried to figure
out what was calling assemble_name without marking the the decl as 
referenced.
I finally figured out where the problem was since I knew it was related 
to
outputing of function decls so I looked again for assemble_name and 
found
the macro ASM_OUTPUT_FDESC in the header file was calling assemble_name
but not setting the function decl as referenced.  This patch fixes the
problem.

Applied as approved by Zack after Andreas Schwab tested it for me
as I do not have access to a IA64 machine.

Thanks,
Andrew Pinski
