The loop is:
# mask_12 = PHI <mask_26(3), mask_6(1)>;
<L0>:;
__m2_11 = VIEW_CONVERT_EXPR<vector int>(0);
D.1667_18 = VIEW_CONVERT_EXPR<vector signed char>(__m2_11);
D.1668_19 = VIEW_CONVERT_EXPR<vector signed char>(D.1659_15);
D.1669_20 = __builtin_ia32_punpcklbw (D.1668_19, D.1667_18);
mask_26 = mask_12 + 4B;
if (end_7 > mask_26) goto <L10>; else goto <L2>;
so tree-ssa-loop-im is not handling VCE at all.
