fb66541e63 Change ValueTable to use a DenseMap for mapping expressions to value numbers.
This results in a slight speedup for 403.gcc.

b97819852a Move some sets and maps to SmallPtrSet and DenseMap respectively. This
reduces the time to optimize 403.gcc from 17.6s to 16.4s.

a8a8a36629 After a basic block is split into two parts,
second part dominates all the blocks dominated
by original basic block. And first part dominates
second part.

64d80e3387 Change instruction description to split OperandList into OutOperandList and
InOperandList. This gives one piece of important information: # of results
produced by an instruction.
An example of the change:
def ADD32rr  : I<0x01, MRMDestReg, (ops GR32:$dst, GR32:$src1, GR32:$src2),
                 "add{l} {$src2, $dst|$dst, $src2}",
                 [(set GR32:$dst, (add GR32:$src1, GR32:$src2))]>;
=>
def ADD32rr  : I<0x01, MRMDestReg, (outs GR32:$dst), (ins GR32:$src1, GR32:$src2),
                 "add{l} {$src2, $dst|$dst, $src2}",
                 [(set GR32:$dst, (add GR32:$src1, GR32:$src2))]>;

this situation, make a normal call to malloc().

b63c7b695f Turn on FastDSE by default.
Note: FastDSE now equals or exceeds the results of old DSE on all of SPEC2000 and SPEC2006. Unless major problems
show up in the testers, it will likely completely replace old DSE in the near future.
