Justin Lebar ed1e312f05 [NVPTX] Remove NVPTXFavorNonGenericAddrSpaces pass.
Summary:
This has been replaced by the NVPTXInferAddressSpaces pass.  We've had
the new one as the default with the old one accessible via a flag for
some months now, and we've had no problems.

Jingyue Wu cd3afea451 Add NVPTXLowerAlloca pass to convert alloca'ed memory to local address
Summary:
This is done by first adding two additional instructions to convert the
alloca returned address to local and convert it back to generic. Then
replace all uses of alloca instruction with the converted generic
address. Then we can rely NVPTXFavorNonGenericAddrSpace pass to combine
the generic addresscast and the corresponding Load, Store, Bitcast, GEP
Instruction together.
