deficiencies exist:

- Works only if ABI is o32.
- Zero-sized structures cannot be passed.
- There is a lot of redundancy in generated code.

b4d8d31e59 Simplify offset calculation of stack frame objects for $gp restore location and
variable arguments in LowerCall and LowerFormalArguments. This should also fix
the bug in which handling of variable arguments is incorrect when the front-end
optimizes away unused fixed arguments.

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.
