[patch] Allocate identifier node for user-specified assembler names

["John David Anglin" <dave at hiauly1 dot hia dot nrc dot ca>]

In debugging the problems associated with Bug c++/19797, I found that
we fail to create an identifier node for the real, unstarred, name of
a user-specified assembler name.  As a result, a call to assemble_name
doesn't mark the real name as referenced.  The HP linker is very picky
in requiring that all external functions be imported (typed).  We need
all external references marked when used to fix the above PR correctly.

I'm not quite sure if this is the best place to create the identifier
node but it's where the node for the starred name is created.

Tested on i686-pc-linux-gnu, hppa2.0w-hp-hpux11.11, hppa64-hp-hpux11.11
and hppa-unknown-linux-gnu with no regressions.

Ok for 4.0 and 4.1 branches?

Dave
