of the initializer is valid before using it.

Fixes rdar://12455002&12449015 where local variables of objc objects in ARC mode
were not annotated because of the ImplicitValueInitExpr initializer having invalid
source range, resulting in the SourceRange of the VarDecl having invalid end location.

With this patch Bitrig can use a different c++ library without pain and
within the normal commandline parameters.

Original patch by David Hill, with lots of fixes and cleanup by me.

The darwin change should be a nop since Triple::getArchTypeForDarwinArchName
doesn't know about amd64.

If things like amd64-mingw32 are to be rejected, we should print a error
earlier on instead of silently using the wrong abi.

Remove old comment that looks out of place, this is "in clang".

GCC has always supported this on PowerPC and 4.8 supports it on all platforms,
so it's a good idea to expose it in clang too. LLVM supports this on all targets.

The Clang ASTs are a DAG, not a pure tree. However, ParentMap has to
choose a single parent for each object. In the main (only?) cases in
which the AST forms a DAG, it protects from multiple traversal by using
OpaqueValueExprs. Previously, ParentMap would just unconditionally look
through all OpaqueValueExprs when building its map.

In order to make this behavior better for the analyzer's diagnostics,
ParentMap was changed to not set a statement's parent if there already
was one in the map. However, ParentMap is supposed to allow updating
existing mappings by calling addStmt once again. This change makes the
"transparency" of OpaqueValueExprs explicit, and disables it when it
is not desired, rather than checking the current contents of the map.

This new code seems like a big change, but it should actually have
essentially the same performance as before. Only OpaqueValueExprs and
their users (PseudoObjectExpr and BinaryConditionalOperator) will
have any different behavior.

There should be no user-visible functionality change, though a test
has been added for the current behavior of BinaryConditionalOperator
source locations and accompanying Xcode arrows (which are not so great...).

Some implicit statements, such as the implicit 'self' inserted for "free"
Objective-C ivar access, have invalid source locations. If one of these
statements is the location where an issue is reported, we'll now look at
the enclosing statements for a valid source location.

to not mess up with module building.

It was not worth trying to combine indexing without preprocessing record
and building modules with one because:

-just importing a module/PCH that was built with a pp record, enables it anyway
-the performance gain of indexing without the preprocessing record is insignificant.
