Debuginfo: Fix nested variables (primarily for CodeView) (#2909) 
We've been going back and forth between GEPs and complex DWARF
expressions based on the context pointer; this goes back to the latter,
as that fixes simple nested variables for CodeView with LLVM >= 6.

I guess it also helps for debuginfos of nested vars with enabled
optimizations.

e0319eadf1 Add DI namespaces & use them for templates and C++ namespaces 
And make sure the template instance names include the template
parameters, a regression after #2826.

Also prevent `TemplatedSymbol(...).TemplatedSymbol` names, just use
`TemplatedSymbol!(...)` instead.

9facf5ad28 Debug info: better handling of static aggregate members with DIFlagStaticMember 
Once again closer to GDC and Clang's output, and attaching static variables to the module scope prevents an assert from triggering in IR/DIBuilder.cpp:

  checkGlobalVariableScope(): Assertion `CT->getIdentifier().empty() && "Context of a global variable should not be a type with identifier"'

2cdae62b0e Debug info: attach entries to their scope, and never use the qualified name except for modules 
Previously entries were made children of the compile unit, and both global and imported symbols were only accessible by using their mangled name, or since the latest commit by their qualified name.

This brings the DWARF output closer to GDC's.

3338bbf9c0 DIType for types involving classes were incorrect in some cases. 
Static arrays of classes, pointers to class (and perhaps global class variables) ended up with a wrong DIType because of wrong CreateTypeDescription() calls for class types.

Ex.: Array!FuncDeclaration caused an infinite recursion crash in GDB, because for its « FuncDeclaration[SMALLARRAYCAP] smallarray » field DIBuilder::CreateSArrayType() had DIBuilder return a value type instead of a reference type for FuncDeclaration.

7ac1216292 Nested variables debug info fixes. 
- Fix the value of closure variables in the parent function. Previously the passed value was the GEP instruction into .frame, and that instruction corresponds to a register  so resulted in "DWARF-2 expression error: DW_OP_reg operations must be used either alone(...)" (also the address was incorrect anyway because the offset would get doubled by 'addr')

 - When emitting debug info for a parent function parameter that is accessed from a nested function, call DIBuilder.createAutoVariable instead of createParameterVariable. Two different variables for the same parameter index was triggering an assert in llvm::DbgVariable::addMMIEntry. This fixes the compilation of druntime and phobos when building against LLVM 3.8.
