[PATCH] D12166: Assign weights to edges to jump table when lowering switch statement.

[Cong Hou via llvm-commits]

congh added a comment.

Change the type of weight from uint64_t to uint32_t as there won't be overflow in calculation.

Add a test case that checks if the edge weight to the jump table is correct.
