Use uint64_t for branch weights instead of uint32_t
CallInst::updateProfWeight() creates branch_weights with i64 instead of i32. To be more consistent everywhere and remove lots of casts from uint64_t to uint32_t, use i64 for branch_weights. Reviewed By: davidxl Differential Revision: https://reviews.llvm.org/D88609
