Summary:
Code to import "ctor initializers" at import of functions
is moved to be after the flags in the newly created function
are imported. This fixes an error when the already created but
incomplete (flags are not set) function declaration is accessed.

Summary:
The default expression of a parameter variable should be imported before
the parameter variable object is created. Otherwise the function is created
with an incomplete parameter variable (default argument is nullptr) and in
this intermediary state the expression is imported. This import can have
a reference to the incomplete parameter variable that causes crash.

Summary:
When searching for a declaration to be loaded the "lookup name" for every
other Decl is computed. If the USR can not be determined here should be
not an assert, instead skip this Decl.

Summary:
The existing CTU mechanism imports `FunctionDecl`s where the definition is available in another TU. This patch extends that to VarDecls, to bind more constants.
- Add VarDecl importing functionality to CrossTranslationUnitContext
- Import Decls while traversing them in AnalysisConsumer
- Add VarDecls to CTU external mappings generator
- Name changes from "external function map" to "external definition map"

Summary:
When importing classes we may add a CXXMethodDecl more than once to a CXXRecordDecl when handling overrides. This patch will fix the cases we currently know about and handle the case where we are only dealing with declarations.

This patch introduces the ability to test an arbitrary sequence of imports
between a given set of virtual source files. This should finally allow
us to write simple tests and fix annoying issues inside ASTImporter
that cause failures in CSA CTU. This is done by refactoring
ASTImporterTest functions and introducing `testImportSequence` facility.
As a side effect, `testImport` facility was generalized a bit more. It
should now allow import of non-decl AST nodes; however, there is still no
test using this ability.
As a "test for test", there is also a fix for import anonymous TagDecls
referred by typedef. Before this patch, the setting of typedef for anonymous
structure was delayed; however, this approach misses the corner case if
an enum constant is imported directly. In this patch, typedefs for
anonymous declarations are imported right after the anonymous declaration
is imported, without any delay.
Thanks to Adam Balogh for suggestions included into this patch.

Originally submitted as r326323 and r326324.
Reverted in r326432.
Reverting the commit was a mistake.
The breakage was due to invalid build files in our internal buildsystem,
CMakeLists did not have any cyclic dependencies.
llvm-svn: 326439
Also revert "[analyzer] Fix a compiler warning"
This reverts commits r326323 and r326324.
Reason: the commits introduced a cyclic dependency in the build graph.
This happens to work with cmake, but breaks out internal integrate.

The aim of this patch is to be minimal to enable incremental development of
the feature on the top of the tree. This patch should be an NFC when the
feature is turned off. It is turned off by default and still considered as
experimental.
Technical details are available in the EuroLLVM Talk:
http://llvm.org/devmtg/2017-03//2017/02/20/accepted-sessions.html#7
Note that the initial prototype was done by A. Sidorin et al.: http://lists.llvm.org/pipermail/cfe-dev/2015-October/045730.html
Contributions to the measurements and the new version of the code: Peter Szecsi, Zoltan Gera, Daniel Krupp, Kareem Khazem.
