nv50,nvc0: handle TGSI_PROPERTY_VS_WINDOW_SPACE_POSITION
nv50,nvc0: handle NULL vertex elements without fallback
nv50/ir/tgsi: implement TGSI_OPCODE_NRM,DP2A

Used by d3d9 st.
nv50: don't emit buffer for skipped vertex elements

Grr, should forbid that and insert dummy elements in nine.
nvc0: avoid fault in get_query_result if there was no begin_query
gallium: add PIPE_CAP_DEVICE_MEMORY_SIZE
softpipe: handle PIPE_CAP_DEVICE_MEMORY_SIZE

Because the compile warning is annoying.

Looks like no one's using this thing.
