nv50/ir: constant fold OP_SPLIT

Split the source immediate value into new values and move them into the
original defs set by the split. Since we can only have up to 64-bit
immediates, this is largely beneficial for F64 (and, in the future, U64)
operations.

[imirkin: always use U32, set newi for foldCount tracking]
