As I am going on holidays until August (back only 2 days until then), I thought
I should share my WIP here. No sure that's the right direction, anyway that's
not working yet.

--- Comment #8 from Christophe Lyon ---
Indeed, it's what happens in try_combine():
i2src = subst (i2src, pc_rtx, pc_rtx, 0, 0, 0);
converts i2src
(zero_extend:SI (reg:HI 117))
into:
(and:SI (subreg:SI (reg:HI 117) 0)
(const_int 1 [0x1]))

--- Comment #7 from Christophe Lyon ---
Before the patch:
Trying 8 -> 14:
8: r113:SI=zero_extend(r117:HI)
REG_DEAD r117:HI
14: r0:SI=r113:SI
REG_DEAD r113:SI
Successfully matched this instruction:
(set (reg/i:SI 0 r0)

--- Comment #6 from Christophe Lyon ---
Before r12-671 before combine we have:
(insn 7 4 8 2 (set (reg:HI 117)
(unspec:HI [
(reg/v:V16QI 115 [ v ])
(reg/v:V16QI 116 [ w ])
] VCMPEQQ_S))

Before the patch, combine says:
allowing combination of insns 8 and 14
original costs 4 + 2 = 6
replacement cost 4
deferring deletion of insn with uid = 8.
modifying insn i314:
