Previously we relied on the presence of a member which needs no initialization
to prevent us from creating an additional initialization of the outer anonymous
union field. We have already correctly marked that field as initialized by the
member of the union (repeatedly due to the original bug this patch fixes) so we
simply need to bail out.

anonymous union under the presumption that they didn't do anything. While this
is true, our checks for redundant initialization of an anonymous union still
fire when these overlap with explicit user initialization. A cleaner approach
is to avoid initializing multiple members of a union altogether, but this still
is in a rather fuzzy are especially when C++0x allows non-POD types into
unions.

InlineSpiller inserts loads and spills immediately instead of deferring to
VirtRegMap. This is possible now because SlotIndexes allows instructions to be
inserted and renumbered.

This is work in progress, and is mostly a copy of TrivialSpiller so far. It
works very well for functions that don't require spilling.

initialization. I tried several ideas but couldn't come up with a test case for
this that didn't rely on a Clang bug to report a diagnostic after template
instantiation of the constructor due to the implicit initializers. Suggestions
welcome. This fixes the source location aspect of PR7402.

This commit 'introduces' a slightly different way to restore the state of the AST object.
It makes PCHDeclReader/PCHDeclWriter friends and gives them access to the private members of the object.
The rationale is to avoid using/modifying the AST interfaces for PCH read/write so that to:

-Avoid complications with objects that have side-effects during creation or when using some setters.
-Not 'pollute' the AST interface with methods only used by the PCH reader/writer
-Allow AST objects to be read-only.

When we know that we are at sub-statement reading (which is all of PCHStmtReader) use the "faster" ReadSubStmt. No functionality change.

but not for compound assignment.

metadata types which should be marked as "weak", but which the linker will
remove upon final linkage. For example, the "objc_msgSend_fixup_alloc" symbol is
defined like this:

       .globl l_objc_msgSend_fixup_alloc
       .weak_definition l_objc_msgSend_fixup_alloc
       .section __DATA, __objc_msgrefs, coalesced
       .align 3
l_objc_msgSend_fixup_alloc:
        .quad   _objc_msgSend_fixup
        .quad   L_OBJC_METH_VAR_NAME_1

This is different from the "linker_private" linkage type, because it can't have
the metadata defined with ".weak_definition".
