7436b57de3 Avoid creating a token factor node in trivially redundant cases. This
eliminates almost one node per block in common cases.

7c0104b525 Handle GEP's a bit more intelligently. Fold constant indices early and
turn power-of-two multiplies into shifts early to improve compile time.

a32551197a Change the ValueList array for each node to be shared instead of individuallyallocated. Further, in the common case where a node has a single value, justreference an element from a small array. This is a small compile-time win.

65113b2f86 Switch the operandlist/valuelist from being vectors to being just an array.This saves 12 bytes from SDNode, but doesn't speed things up substantially
(our graphs apparently already fit within the cache on my g5).  In any case
this reduces memory usage.

f469cb6546 Clean up RemoveDeadNodes significantly, by eliminating the need for a temporary
set and eliminating the need to iterate whenever something is removed (which
can be really slow in some cases).  Thx to Jim for pointing out something silly
I was getting stuck on. :)

arbitrarily aligned dynamic allocas coming soon.
