Fixes #85382.
Currently,
assertionFailure()crashes at-Onone -assert-config Releasebecause it used@inlinable @inline(__always)instead of@_transparent. At-Onone, this caused a call to the pre-compiled stdlib (built in Debug mode) instead of inlining.To address this, we change it to
@_transparentfor mandatory inlining at all optimization levels, consistent withassert(),precondition(), andpreconditionFailure().
