Lionel Landwerlin aa53665fda intel/fs/copy_prop: check stride constraints with actual final type 
In some cases we will change the type of the destination register of
an instruction. This is the type we should use to verify that we're
allow to do the replacement.

Otherwise we can hit restrictions on CHV and upcoming Xe-Hp for
instance where the copy propagation transforms this :

send(16) (mlen: 2) vgrf10:UD, 0u, 0u, vgrf35:D, null:UD
mov(16) vgrf11:UW, vgrf10<2>:UW
mov(16) vgrf12:UW, vgrf10+0.2<2>:UW
mov(16) vgrf15:HF, |vgrf11|:HF
mov(16) vgrf16:HF, |vgrf12|:HF
mov(8) vgrf41<2>:UW, vgrf15+0.0:UW group0
mov(8) vgrf42<2>:UW, vgrf15+0.16:UW group8
mov(8) vgrf45<2>:UW, vgrf16+0.0:UW group0
mov(8) vgrf46<2>:UW, vgrf16+0.16:UW group8

into this :

send(16) (mlen: 2) vgrf10:UD, 0u, 0u, vgrf35:D, null:UD
mov(8) vgrf41<2>:HF, |vgrf10+0.0|<2>:HF group0
mov(8) vgrf42<2>:HF, |vgrf10+1.0|<2>:HF group8
mov(8) vgrf45<2>:HF, |vgrf10+0.2|<2>:HF group0
mov(8) vgrf46<2>:HF, |vgrf10+1.2|<2>:HF group8

Because of the floating point use, stride and offets should be the
same.

v2: Fix final destination type selection (Curro)

v3: constify (Curro)
