[LiveVariables] Mark use without implicit if defined at instr (#119446)
LiveVariables will mark instructions with their implicit subregister
uses. However, it will also mark the subregister as an implicit if its
own definition is a subregister of it, i.e. `$r3 = OP val, implicit-def
$r0_r1_r2_r3, ..., implicit $r2_r3`, even if it is otherwise unused,
which defines $r3 on the same line it is used.
This change ensures such uses are marked without implicit, i.e. `$r3 =
OP val, implicit-def $r0_r1_r2_r3, ..., $r2_r3`.
