[PATCH]Add symbol whose field 'has_type' has been set to partial symbol table

[Jun Gong <heixia108 at gmail dot com>]

This patch intends to add symbol whose field 'has_type' has been set
to partial symbol table.

The patch and corresponding test case have been discussed and reviewed
before at https://sourceware.org/ml/gdb-patches/2013-10/msg00747.html
and https://sourceware.org/ml/gdb-patches/2013-11/msg00003.html.
However it has not been committed because Tom Tromey is very busy and
could not help commit it now. I have received copyright assignment.
Could you help review and commit the patch? Thank you!

The following are the summary of the patch, and the attachment
const-var.exp is test case.
