- Unify the handling of promoted args when assigning offsets; there's no need to handle independent vs. dependent promotion separately. - Use `varTypeUsesFloatReg` where appropriate. - Some minor refactoring of initial reg assignment. These changes are preparatory to improved struct promotion for args. - Add a 'Clear' method to `StructPromotionHelper` for use after inlining (not yet in use, as it produces diffs). - Wrap a SIMD field node in `GT_OBJ` only if needed. -

Nit: it looks like the header was not updated for this function.

Thanks for catching that; rather than fix in this PR, I've fixed it in the follow-up PR #39326 which I'll rebase on this once this one's merged.
