d3ac47f805 Reverse order of operands of address operand mem so that the base operand comes
before the offset. This change will enable simplification of function
MipsRegisterInfo::eliminateFrameIndex.

25eba399cb Change the chain input of nodes that load the address of a function. This change
enables SelectionDAG::getLoad at MipsISelLowering.cpp:1914 to return a
pre-existing node instead of redundantly create a new node every time it is
called.

4e694c96f1 This patch implements atomic intrinsics atomic.load.add (sub,and,or,xor,
nand), atomic.swap and atomic.cmp.swap, all in i8, i16 and i32 versions.
The intrinsics are implemented by creating pseudo-instructions, which are
then expanded in the method MipsTargetLowering::EmitInstrWithCustomInserter.

69c19f7316 Change StackDirection from StackGrowsUp to StackGrowsDown.
The following improvements are accomplished as a result of applying this patch:
- Fixed frame objects' offsets (relative to either the virtual frame pointer or
  the stack pointer) are set before instruction selection is completed. There is
  no need to wait until Prologue/Epilogue Insertion is run to set them.
- Calculation of final offsets of fixed frame objects is straightforward. It is
  no longer necessary to assign negative offsets to fixed objects for incoming
  arguments in order to distinguish them from the others.
- Since a fixed object has its relative offset set during instruction
  selection, there is no need to conservatively set its alignment to 4.
- It is no longer necessary to reorder non-fixed frame objects in 
  MipsFrameLowering::adjustMipsStackFrame.

43299776d7 Change the order fixed objects are created in MipsTargetLowering::LowerCall in
preparation for reversing StackDirection.

Fixed objects are created in the following order:  
 1. Incoming arguments passed on stack.
 2. va_arg objects (include both arguments that are passed in registers and
    pointer to the location of the first va_arg argument).
 3. $gp restore slot.
 4. Outgoing arguments passed on stack.
 5. Pointer to alloca'd space.
