The member init list for the sole constructor for CodeGenFunction
has gotten out of hand, so this patch moves the non-parameter-dependent
initializations into the member value inits.

FunctionProtoType.
We previously re-evaluated the expression each time we wanted to know whether
the type is noexcept or not. We now evaluate the expression exactly once.
This is not quite "no functional change": it fixes a crasher bug during AST
deserialization where we would try to evaluate the noexcept specification in a
situation where we have not deserialized sufficient portions of the AST to
permit such evaluation.

There are only a few cases of importing a frienddecl which is currently supported.
This patch aims to improve the friend import process.
Set FriendObjectKind in case of decls, insert friend into the friend chain
correctly, checks structurally equivalent in a more advanced manner.
Test cases added as well.

Previously UnaryTransformType nodes were comparing the same node
for structural equivalence. This was due to a typo where T1 was
on both sides of the comparison. This patch corrects that typo.
Unfortunately I couldn't find a way to test this change. It seems
that currently UnaryTransform nodes are never actually checked
for equivalence, only their canonical types are.
None the less, this correction seemed appropriate.

Also, a number of style and bug fixes was done:
* ASTImporterTest: added sanity check for source node
* ExternalASTMerger: better lookup for template specializations
* ASTImporter: don't add templated declarations into DeclContext
* ASTImporter: introduce a helper, ImportTemplateArgumentListInfo getting SourceLocations
* ASTImporter: proper set ParmVarDecls for imported FunctionProtoTypeLoc

This patch relates to: https://reviews.llvm.org/D33666 This adds support
for template parameters to be passed to the address_space attribute.
The main goal is to add further flexibility to the attribute and allow
for it to be used easily with templates.
The main additions are a new type (DependentAddressSpaceType) alongside
its TypeLoc and its mangling. As well as the logic required to support
dependent address spaces which mainly resides in TreeTransform.h and
SemaType.cpp.

Allow ODR for ObjC/C in the sense that we won't keep more that
one definition around (merge them). However, ensure the decl
pass the structural compatibility check in C11 6.2.7/1, for that,
reuse the structural equivalence checks used by the ASTImporter.
Few other considerations:
- Create error diagnostics for tag types mismatches and thread
them into the structural equivalence checks.
- Note that by doing this we only support redefinition between types
that are considered "compatible types" by C.
This is mixed approach of the suggestions discussed in
http://lists.llvm.org/pipermail/cfe-dev/2017-March/053257.html

ASTImporter has some bugs when it's importing types
that themselves come from an ExternalASTSource. This
is exposed particularly in the behavior when
comparing complete TagDecls with forward
declarations. This patch does several things:
- Adds a test case making sure that conflicting
forward-declarations are resolved correctly;
- Extends the clang-import-test harness to test
two-level importing, so that we make sure we
complete types when necessary; and
- Fixes a few bugs I found this way. Failure to
complete types was one; however, I also discovered
that complete RecordDecls aren't properly added to
the redecls chain for existing forward
declarations.

Create a header and impl file for the structural equivalence context.
This is to allow other users outside clang importer. NFCI
