Auto merge of #80718 - tmiasko:skip-opt-mir, r=oli-obk
Consistently avoid constructing optimized MIR when not doing codegen The optimized MIR for closures is being encoded unconditionally, while being unnecessary for cargo check. This turns out to be especially costly with MIR inlining enabled, since it triggers computation of optimized MIR for all callees that are being examined for inlining purposes https://github.com/rust-lang/rust/pull/77307#issuecomment-751915450. Skip encoding of optimized MIR for closures, enum constructors, struct constructors, and trait fns when not doing codegen, like it is already done for other items since 49433.
