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.

to where we were previously.

functionality change here is that we recover a little more
aggressively from ill-formed switch conditions.

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.
 - Also, tidy up assignment code a bit to look more like the scalar path.

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".

we do properly implement CFG support for @try...@catch.

SmallArray[SmallSize] in the SmallPtrSetIteratorImpl, and this is
one off the end of the array.  For those who care, right now gcc
warns about writing off the end because it is confused about the
declaration of SmallArray as having length 1 in the parent class
SmallPtrSetIteratorImpl.  However if you tweak code to unconfuse
it, then it still warns about writing off the end of the array,
because of this buffer overflow.  In short, even with this fix
gcc-4.6 will warn about writing off the end of the array, but now
that is only because it is confused.

and make PATypeHolder work with null pointers.

The implicitly generated one didn't work on numerous levels, but was still
accepted, allowing all sorts of bugs with default constructed pa type holders.

Previously, they "sort of" worked if they were default constructed and then
destructed.  Now they really work, and you can even default construct one,
then assign to it, amazing.

A partial redefine needs to be treated like a tied operand, and the register
must be reloaded while processing use operands.

This fixes a bug where partially redefined registers were processed as normal
defs with a reload added. The reload could clobber another use operand if it was
a kill that allowed register reuse.

The LowerSubregs pass needs to preserve implicit def operands attached to
EXTRACT_SUBREG instructions when it replaces those instructions with copies.
