Correct disassembly of dot product instructions.
Dot products deviate from the normal disassembly rules for lane indexed
instruction. Their canonical representation is in the form of:
v0.2s, v0.8b, v0.4b[0] instead of v0.2s, v0.8b, v0.b[0] to try to denote
that these instructions select 4x 1 byte elements instead of a single 1 byte
element.
Previously we were disassembling them following the normal rules, this patch
corrects the disassembly.
