// Always enable inlining MIR when building the standard library.
// Without this flag, MIR inlining is disabled when incremental compilation is enabled.
// That causes some mir-opt tests which inline functions from the standard library to
// break when incremental compilation is enabled. So this overrides the "no inlining
// during incremental builds" heuristic for the standard library.
