re PR tree-optimization/85467 (ICE: verify_gimple failed: non-trivial conversion at assignment with -O2 -fno-tree-ccp --param=sccvn-max-scc-size=10)
PR tree-optimization/85467
* fold-const.c (fold_ternary_loc) <case BIT_FIELD_REF>: Use
VECTOR_TYPE_P macro. If type is vector type, VIEW_CONVERT_EXPR the
VECTOR_CST element to type.
* gcc.dg/pr85467.c: New test.
