The DwarfWriter expects DbgScopes and DIEs to behave themselves according to
DwarfWriter's rules. However, inlined functions violate these rules. There are
two different types of DIEs associated with an inlined function: an abstract
instance, which has information about the original source code for the function
being inlined; and concrete instances, which are created for each place the
function was inlined and point back to the abstract instance.

This patch tries to stay true to this schema. It bypasses how regular DbgScopes
and DIEs are created and used when necessary. It provides special handling for
DIEs of abstract and concrete instances.

This doesn't take care of all of the problems with debug info for inlined
functions, but it's a step in the right direction. For one thing, llvm-gcc
generates wrong IR (it's missing some llvm.dbg intrinsics at the point where the
function's inlined) for this example:

#include <stdio.h>
static __inline__ __attribute__((always_inline))  int bar(int x) { return 4; }
void foo() {
  long long b = 1;
  int Y = bar(4);
  printf("%d\n", Y);
}

while clang generates correct IR.

template. The injected-class-name is either a type or a template,
depending on whether a '<' follows it. As a type, the
injected-class-name's template argument list contains its template
parameters in declaration order.

As part of this, add logic for canonicalizing declarations, and be
sure to canonicalize declarations used in template names and template
arguments. 

A TagType is dependent if the declaration it references is dependent.

I'm not happy about the rather complicated protocol needed to use
ASTContext::getTemplateSpecializationType.

reason for this code to be separated out between the different opt levels, as it
was doing pretty much the same thing anyway.

Modify getLValueElement accordingly. Now we don't require base region 
to be a typed region. Do not create TypedViewRegion when base region is 
symbolic or alloca region. We can do so because each element region has 
its type information.
