Thanks @jeanPerier, that makes sense. I revised the patch to keep the O0 behavior narrower.

At O0, `InlineHLFIRAssign` now only handles scalar-RHS to array-LHS broadcasts. Array-to-array assignments still fall back to `_FortranAAssign`, so the existing conformity checks/code-size/debug behavior is preserved.

At O1+, the full pass still runs as before, with scalar RHS support added.
