[Hexagon] Fix assert with packetizing IMPLICIT_DEF instructions
The compiler is generating packet with the following instructions,
which causes an undefined register assert in the verifier.
$r0 = IMPLICIT_DEF
$r1 = IMPLICIT_DEF
S2_storerd_io killed $r29, 0, killed %d0
The problem is that the packetizer is not saving the IMPLICIT_DEF
instructions, which are needed when checking if it is legal to
add the store instruction. The fix is to add the IMPLICIT_DEF
instructions to the CurrentPacketMIs structure.
Patch by Brendon Cahoon.
