lists.  This reduces isel time on kc++ from 2.6164 to 2.5570s, about 2.3%.

an SDNode to be allocated as part of the node itself, instead of being a
separate new[]'d object.  Switch HandleSDNode, LoadSDNode, and StoreSDNode
to use this mechanism.  This saves one heap allocation and free for each node
of this type that is allocated.  This reduces isel time from 2.7638 to 2.6164s
on kc++, which is a 5.6% speedup.

Make llvm-upgrade valgrind clean. Deleting type instances is a really
nasty thing to do to LLVM. This was a hold-over from the re-write.
This fixes test/Assembler/2007-01-22-UpgradeTypeMapInvalidMemory.ll and
potentially many other bugs.

Removing -raise has neglible positive or negative side effects so we are
opting to remove it. See the PR for comparison details.

move the sections of the class-h around in the right order, make it actually
reflect the classes in LLVM today.
