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).
