We only need to track slot for predicated stores and predicated HVX
instructions.
Add arguments to the probe helper functions to indicate if the slot
is predicated.
Here is a simple example of the differences in the TCG code generated:
IN:
0x00400094: 0xf900c102 { if (P0) R2 = and(R0,R1) }
BEFORE
---- 00400094
mov_i32 slot_cancelled,$0x0
mov_i32 new_r2,r2
and_i32 tmp0,p0,$0x1
brcond_i32 tmp0,$0x0,eq,$L1
and_i32 tmp0,r0,r1
mov_i32 new_r2,tmp0
br $L2
set_label $L1
or_i32 slot_cancelled,slot_cancelled,$0x8
set_label $L2
mov_i32 r2,new_r2
AFTER
---- 00400094
mov_i32 new_r2,r2
and_i32 tmp0,p0,$0x1
brcond_i32 tmp0,$0x0,eq,$L1
and_i32 tmp0,r0,r1
mov_i32 new_r2,tmp0
br $L2
set_label $L1
set_label $L2
mov_i32 r2,new_r2
