ca56feaf38 add a new setNumChildren method for resizing scopes. Tweak getHash() so
that we never return a tombstone value, which (thankfully) triggers an
assert in densemap.

d6c84720df change the scope node to include a list of children to be checked
instead of to have a chained series of scope nodes.  This makes
the generated table smaller, improves the efficiency of the
interpreter, and make the factoring optimization much more 
reasonable to implement.

04db82d2ba Implement the first half of redundancy factoring: efficiently
splitting all the patterns under scope nodes into equality sets
based on their first node.  The second step is to rewrite the
graph info a form that exposes the sharing.  Before I do this, 
I want to redesign the Scope node.

movechild/record -> recordchild/movechild and 
movechild/moveparent -> noop xforms.  This slightly shrinks the tables
(x86 to 117454) and enables adding future improvements.

c84edb7bdd Since the new instruction selector now works, I don't need to keep
the old one around for comparative purposes: have the
ENABLE_NEW_ISEL #define (which is not enabled on mainline) stop
emitting the old isel at all, yay for build time win.

19b5a7590b implement a simple proof-of-concept optimization for

02f73585f7 The new isel was not properly handling patterns that covered
internal nodes with flag results.  Record these with a new 
OPC_MarkFlagResults opcode and use this to update the interior
nodes' flag results properly.  This fixes CodeGen/X86/i256-add.ll
with the new isel.

1afba8e474 Implement order-preserving option forwarding.
Needed to correctly handle things like 'llvmc -framework Foo foo.o -framework
Bar bar.o' - before this commit all '-framework' options would've been grouped
together in the beginning.

Due to our dependence on CommandLine this turned out to be a giant hack; we will
migrate away from CommandLine eventually.

565a6f9480 fix most of the failures in the x86 suite by handling multiple
result nodes correctly.  Note that this includes a horrible hack
in DAGISelHeader which cannot be fixed reasonably without

can't be done until we support writing multiple result patterns
for the X86and_flag and related multiple-result nodes.
