Expand description
This function converts an interpreter value into a MIR constant.
The for_diagnostics
flag turns the usual rules for returning ConstValue::Scalar
into a
best-effort attempt. This is not okay for use in const-eval sine it breaks invariants rustc
relies on, but it is okay for diagnostics which will just give up gracefully when they
encounter an Indirect
they cannot handle.
