[InstCombine] Update InstCombine to use poison instead of undef for shufflevector's placeholder (3/3)
This patch is for fixing potential shufflevector-related bugs like D93818.
As D93818, this patch change shufflevector's default placeholder to poison.
To reduce risk, it was divided into several patches, and this patch is for InstCombineVectorOps.

[INSTCOMBINE] Transform reduction(shuffle V, poison, unique_mask) to reduction(V).
After SLP + LTO we may have have reduction(shuffle V, poison,
mask). This can be simplified to just reduction(V) if the mask is only
for single vector and just all elements from this vector are permuted,
without reusing, replacing with undefs and/or other values, etc.
