9a6a882979 Constant-fold ptrtoint+add+inttoptr to gep when the pointer is an 
array and the add is within range. This helps simplify expressions
expanded by ScalarEvolutionExpander.

b81e43b8c3 Factor out a common base class between SCEVCommutativeExpr and 
SCEVAddRecExpr. This eliminates redundant code for visiting
all the operands of an expression.

dee50585e0 Use stable_sort instead of plain sort to avoid the risk of generating 
trivially different code on different hosts (due to differing
std::sort implementations).

b2cf4944c2 Use X86AddrNumOperands instead of magic constant one 
more place.  This fixes a bunch of x86-64 JIT regressions.
(Introduced when the value of the magic constant changed
in 68645.  At the time apparently nobody noticed; failures
were hidden in 70343-70439 by an unrelated bug, so showed
up again as "new" failures in 70440.)

b71ad70b4e Fix PR3754: don't mark functions that wrap MallocInst with 
the readnone.  Since MallocInst is scheduled for deletion
it doesn't seem worth doing anything more subtle, such as
having mayWriteToMemory return true for MallocInst.

5e839321f2 If a MachineBasicBlock has multiple ways of reaching another block,

9aad2bbcf9 Allow multiclass def names to contain "#NAME"" where TableGen replaces 
#NAME# with the name of the defm instantiating the multiclass.  This is
useful for AVX instruction naming where a "V" prefix is standard
throughout the ISA.  For example:

multiclass SSE_AVX_Inst<...> {
   def SS : Instr<...>;
   def SD : Instr<...>;
   def PS : Instr<...>;
   def PD : Instr<...>;

   def V#NAME#SS : Instr<...>;
   def V#NAME#SD : Instr<...>;
   def V#NAME#PS : Instr<...>;
   def V#NAME#PD : Instr<...>;
}

defm ADD : SSE_AVX_Inst<...>;

Results in 

ADDSS
ADDSD
ADDPS
ADDPD

VADDSS
VADDSD
VADDPS
VADDPD
