gdb/92: Nuke CONST_PTR

[chastain@redhat.com]

Synopsis: Nuke CONST_PTR

State-Changed-From-To: analyzed->closed
State-Changed-By: chastain
State-Changed-When: Wed Feb 13 10:56:35 2002
State-Changed-Why:
    I killed CONST_PTR.
    
    It turned out that other code was not using CONST_PTR.  We've been using plain "const" since 4.18 so it's safe to remove the CONST_PTR facade.
