[PATCH] D70987: [HIP] Improve opt-level handling

The HIP toolchain invokes `llc` without an explicit opt-level, meaning
it always uses the default (-O2). This makes it impossible to use -O1,
for example. The HIP toolchain also coerces -Os/-Oz to -O2 even when
invoking opt, and it coerces -Og to -O2 rather than -O1.

Forward the opt-level to `llc` as well as `opt`, and only coerce levels
where it is required.
