[RFA] Change to pre-expand symtabs

[Keith Seitz <keiths at redhat dot com>]

Hi,

This patch actually does two things, both related to PR symtab/11743 
(for which I've previously submitted various ugly patches). First, it 
switches gdb to search for symtabs by using psymtab pre-expansion.

Second, it strips off overload information from psymtab search names, 
since psymtabs do not contain any of this information to begin with. I 
believe this is going to be the cleanest approach to fixing the 
overload-instance-in-a-psymtab problem (symtab/11743) that we're likely 
to find.

Note that I have not addressed the linespec.c problems specifically 
reported in symtab/11743. This simply gets the non-quoted case working 
(which is a pre-requisite anyway).
