412821284f Add operator= implementations to SparseBitVector, allowing it to be used in GVN. This results 
in both time and memory savings for GVN.  For example, one testcase went from 10.5s to 6s with
this patch.

acddf9d019 Dial down gcc's warnings: don't use 0UL when 0U suffices (and when the 
variables and methods themselves only use unsigned.)

7ed47a1335 Don't attribute in file headers anymore. See llvmdev for the 
discussion of this change.  Boy are my fingers tired. ;-)

8d69b5a113 It helps a lot when you check for the end of your list before randomly 
dereferencing things.

d81ccc2806 Implement offline variable substitution in order to reduce memory 
and time usage.
Fixup operator == to make this work, and add a resize method to DenseMap
so we can resize our hashtable once we know how big it should be.
