TemplateSpecializationType doesn't quite have getDecl(). Need to go
through TemplateName to get a TemplateDecl.

Added test cases for the hasDeclaration() overload for
TemplateSpecializationType. Also introduced the type matcher
templateSpecializationType() used by the new hasDeclaration() test case.

Updated LibASTMatchersReference.

Re-introducing r175532. The has_getDecl metafunction didn't compile with
Visual Studio. This revision uses approaches has_getDecl from a
different angle that isn't a problem for Visual Studio.

Added dedicated tests for the metafunction.

memory intrinsics in the SDAG builder.

When alignment is zero, the lang ref says that *no* alignment
assumptions can be made. This is the exact opposite of the internal API
contracts of the DAG where alignment 0 indicates that the alignment can
be made to be anything desired.

There is another, more explicit alignment that is better suited for the
role of "no alignment at all": an alignment of 1. Map the intrinsic
alignment to this early so that we don't end up generating aligned DAGs.

It is really terrifying that we've never seen this before, but we
suddenly started generating a large number of alignment 0 memcpys due to
the new code to do memcpy-based copying of POD class members. That patch
contains a bug that rounds bitfield alignments down when they are the
first field. This can in turn produce zero alignments.

This fixes weird crashes I've seen in library users of LLVM on 32-bit
hosts, etc.

Also, add matchers isPrivate(), isProtected() and isPublic(), that
restrict the matching of such AccessSpecDecls and all other Decls.

[analyzer] Relax assumption in FindLastStoreBRVisitor that the thing we are looking for is always a VarRegion.

This was triggering assertion failures when analyzing the LLVM codebase.  This
is fallout from r175988.

I've got delta chewing away on a test case, but I wanted the fix to go
in now.

llvm-svn: 176011

r175988 modified the ExplodedGraph trimming algorithm to retain all
nodes for "lvalue" expressions.  This patch refines that notion to
only "interesting" expressions that would be used for diagnostics.

This fixes llvm.org/PR14967 and is generall necessary to avoid
situations where the column limit is exceeded. The challenge is
restricting such lines splits, otherwise clang-format suddenly starts
breaking at bad places.

Before:
ReallyLongReturnType<TemplateParam1, TemplateParam2>
ReallyReallyLongFunctionName(
    const std::string &SomeParameter,
    const SomeType<string,
                   SomeOtherTemplateParameter> &ReallyReallyLongParameterName,
    const SomeType<string,
                   SomeOtherTemplateParameter> &AnotherLongParameterName) {}

After:
ReallyLongReturnType<TemplateParam1, TemplateParam2>
ReallyReallyLongFunctionName(
    const std::string &SomeParameter,
    const SomeType<string, SomeOtherTemplateParameter> &
        ReallyReallyLongParameterName,
    const SomeType<string, SomeOtherTemplateParameter> &
        AnotherLongParameterName) {}

This removes a const_cast hack from PPCRegisterInfo::hasReservedSpillSlot().
The proper place to save the frame index for the CR spill slot is in the
PPCFunctionInfo object, not the PPCRegisterInfo object.

No new test cases, as this just reimplements existing function.  Existing
tests such as test/CodeGen/PowerPC/crsave.ll are sufficient.

The error is a bit strange tbh, but better than crashing.

This is a common pattern with dyn_cast and similar constructs, when the
PHI no longer depends on the select it can often be turned into a simpler
construct or even get hoisted out of the loop.

This required more changes than I originally expected:

- ObjCIvarRegion implements "canPrintPretty" et al
- DereferenceChecker indicates the null pointer source is an ivar
- bugreporter::trackNullOrUndefValue() uses an alternate algorithm
  to compute the location region to track by scouring the ExplodedGraph.
  This allows us to get the actual MemRegion for variables, ivars,
  fields, etc.  We only hand construct a VarRegion for C++ references.
- ExplodedGraph no longer drops nodes for expressions that are marked
  'lvalue'.  This is to facilitate the logic in the previous bullet.
  This may lead to a slight increase in size in the ExplodedGraph,
  which I have not measured, but it is likely not to be a big deal.

I have validated each of the changed plist output.
