Carl Ritson 057934a6d7 [AMDGPU] Fix insert of SIPreAllocateWWMRegs in FastRegAlloc ...

SIPreAllocateWWMRegs was being inserted after RegisterCoalescer
but this pass does not exist during FastAlloc so pre-allocation
pass was never being run.
Insert pre-allocation after TwoAddressInstructionPass instead.
