           Summary: Template instance name wrongly mangled as LName
           Product: D

Fix the problem (dmd 2.030)

DMD wrongly mangles template instance name as LName, not TemplateInstanceName:
--------------------
module test;
template Temp() { struct S {} }
pragma(msg, Temp!().S.mangleof);
--------------------
S4test9__T4TempZ1S
--------------------

In the above example, DMD mangles the template instance Temp!() to "9__T4TempZ". Note the preceding number. According to the spec, template instance name should be mangled without preceding number:
--------------------
SymbolName:
    LName
    TemplateInstanceName

LName:
    Number Name

TemplateInstanceName:
     __T LName TemplateArgs Z
--------------------

This prevents a name demangler from telling the difference between a usual identifier and template instance name. For example, a demangler can recognize "9__T4TempZ" as a valid module name, not a template instance.


The proposed patch fixes mangle(Declaration *sthis) and
TemplateInstance::mangle() (mangle.c).

I forgot to deal with TemplateMixin. It should be mangled as LName.
