6f8f2ec3 - [move-function] Move diagnostics in front of the flag.

[move-function] Move diagnostics in front of the flag. This is safe to do since: 1. _move is already an always emit into client transparent function, so no ABI impact comes from it. 2. _move is underscored so it is a non-stable stdlib API meaning we aren't providing any guarantees here. 3. Code that doesn't use _move will not be effected by this so there isn't an impact on other code. (cherry picked from commit deb454163d303bd5c3068d9e16c02cb181a1c5ba)
