5106dcd078 Implement support for varargs functions without any fixed 
parameters in the CBE by implicitly adding a fixed argument.
This allows eliminating a work-around from DAE.  Patch by
Sylvere Teissier!

e5f76877ae When determining a canonical insert position, don't climb deeper 
into adjacent loops. Also, ensure that the insert position is
dominated by the loop latch of any loop in the post-inc set which
has a latch.

such that the non-VFP versions have no implicit defs of VFP registers.

prologue/epilogue code will try to save and restore them.

dc8446330f "On SPU, variables in the .bss section that are allocated with the .lcomm directive are not aligned on 16 byte boundaries. This causes misaligned loads, as the generated assembly assumes this "default" alignment. 
this patch disables .lcomm in favour of '.local .comm'

Patch by Kalle Raisklia!
