Patch attached.
(I honestly don't know what has happened in these conversion paths
before my commit.)

Subject: [PATCH] swscale/swscale_unscaled: Actually use X2->RGBA64 conversions

The conversion functions were added in
e7382b4d0101f02e61fdf5ad2c48aca500bb413f, yet they were never
really enabled. Found via -ffunction-sections and --gc-sections.
