Subject: [PATCH 1/2] [RISCV] Fix build failure in getIntrinsicInstrCost

bd66fd0 ([CostModel/RISCV] Fix costs of vector [l](lrint|lround))
introduced buildbot failures by using a temporary ArrayRef when a
SmallVector should have been used. Fix this.

Failure: https://lab.llvm.org/buildbot/#/builders/186/builds/11133
