freedreno/ir3: propagate HALF flag across fanout

If we have a fanout (split) meta instruction to split the result of a
vector instruction, propagate the HALF flag back to the original
instruction.  Otherwise result ends up in a full precision register
while instruction(s) that use the result look in a half-precision
register.
