RTABI chapter 4.3.4 specifies __eabi_mem* calls. Specifically, __eabi_memset accepts parameters (ptr, size, value) in a different order than GNU's memset (ptr, value, size), therefore the special lowering in AAPCS mode. Implementation by Evzen Muller.

reimplement memcpy/memmove/memset lowering to use MachinePointerInfo
...
instead of srcvalue/offset pairs. This corrects SV info for mem
operations whose size is > 32-bits.

Implement a bunch more TargetSelectionDAGInfo infrastructure.

EmitTargetCodeForMemmove out of TargetLowering and into
SelectionDAGInfo to exercise this.
