Clean up some names and fix the handling of default sysroots on Windows and
...
other platforms where the textual default of '/' isn't the system's root
directory. We should probably still make the textual default platform specific,
but this should avoid the particularly bad problem with the previous state: we
applied a sysroot of '/' to '/usr/local/google' which added
'//usr/local/include' to the windows header search path, a share on another
machine named 'usr'. Oops.

"Fix" some unintentional fallout from converting
...
the Stmt* visitation in CursorVisitor to be
data-recursive.
Since AnnotationTokensWorker explicitly calls
CursorVisitor::VisitChildren(), it essentially
transforms the data-recursive algorithm in
CursorVisitor back into a non-data recursive one.
This is particularly bad because the data-recursive
algorithm uses more stack space per stack frame,
which can cause us to blow the stack in some cases.
"Fix" this by making the stack that AnnotationTokensWorker
runs in really huge. The real fix is to modify
AnnotationTokensWorker not to do the explicit
recursive call.

Clean up initialization of LangOptions object by splitting part of it into a parent class
...
'LangOptionsBase' that default initializes all flags to 0. Now the ctor of LangOptions
only initializes the flags that might be non-zero (significantly simplifying things).
This also appeases Valgrind on Mac OS X, which no longer reports that one of the flags
may be uninitialized.

Revert r118991.

Elidable CXXConstructExpr should inhibit calling destructor for temporary
that is copied, not the one created. This is because eliding copy constructor
means that the object that was to be copied will be constructed directly in
memory the copy would be constructed in.
