x86: replace/correct bogus "prefix_extra"

In the rdrand and rdseed cases "prefix_0f" is meant instead. For
mmx_floatv2siv2sf2 1 is correct only for the first alternative. For
the integer min/max cases 1 uniformly applies to legacy and VEX
encodings (the UB and SW variants are dealt with separately anyway).
Same for {,V}MOVNTDQA.

Unlike {,V}PEXTRW, which has two encoding forms, {,V}PINSRW only has
a single form in 0f space. (In *vec_extract<mode> note that the
dropped part if the condition also referenced non-existing alternative
2.)

Of the integer compare insns, only the 64-bit element forms are encoded
in 0f38 space.
