X87: [strong] Refactor ObjectStrength into a replacement for strong boolean args

port dd8544495109804c632bfbcefc3c5c701e0a8c43 (r28839)

original commit message:

    Boolean "is_strong" parameters have begun to proliferate across areas where
    strong mode semantics are different. This CL repurposes the existing
    ObjectStrength enum as a replacement for them.
