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.

EXTRACT_SUBREG instructions when it replaces those instructions with copies.

there's an explicit guard on isPolymorphic, and virtual bases don't affect the

If we want to make a copy (or estimate its cost), it is better to use the
smallest class as more efficient operations might be possible.
