eopXD 2cadf84fc8 [RISCV] Pass OptLevel to RISCVDAGToDAGISel correctly ...

Originally, `OptLevel` isn't passed into the `MachineFunctionPass`.
This lets the default parameter of `SelectionDAGISel`, which is
`CodeGenOpt::Default`, be passed in. OptLevelChanger captures the
optimization level with the parameter, and rather not the value
within `TargetMachine`. This lets the optimization be
unintentionally overwriten if other value than `CodeGenOpt::Default`
passed.

This patch fixes this by passing the optimization level rather
than using the default value.
