with bit-fields.

there's an explicit guard on isPolymorphic, and virtual bases don't affect the
key function calculation.  This allows people to call
ASTContext::getKeyFunction on arbitrary classes.

Implement part of the EmptySubobjectMap optimization described in PR6998. We still need to do this for bases.

When checking whether we can place a base subobject at an offset, we don't need to go past the highest offset that's known to contain an empty base subobject.

Turn on the new empty base subobject tracking code. It's a bit faster than the previous code. However, it still has quadratic performance, something which I intend to fix shortly in a subsequent patch.

Rework the way virtual primary bases are added when laying out classes. Instead of doing it as a separate step, we now use the BaseSubobjectInfo and use it when laying out the bases. This fixes a bug where we would either not add a primary virtual base at all, or add it at the wrong offset.

Change RecordLayoutBuilder::LayoutNonVirtualBase to take a BaseSubobjectInfo. No functionality change.

llvm-svn: 105103

Move computing the base subobject info for a class into the RecordLayoutBuilder because we're going to need it to be able to correctly add offsets for primary virtual bases.

 - Docs are fairly sketchy, if someone wants to pore through gcc to look for
   holes I'd appreciate any failing test cases!
