The following instructions have issues with inline constants:
> v_div_fixup_f64
> v_div_fmas_f64
> v_fma_f64

Number of failing lit1 tests (-search=simple) = 156. 

Issue should appear for other sub-targets as well, e.g. gfx8.

Tested with r272673 (git # da10a460d7c98278561225fda90855b303675f35)

Lit tests attached.
