With LLPC, previous investigation has suggested that si-scheduler
interacts badly with SiFormMemoryClauses on an XNACK target in some
games.

That needs further investigation in the future. In the meantime, this
commit adds a target feature to disable SIFormMemoryClauses on a
per-function basis for LLPC to use.
