fold-const.c (fold_convertible_p): Don't return true for conversion of VECTOR_TYPE to same sized integral type.
* fold-const.c (fold_convertible_p): Don't return true
for conversion of VECTOR_TYPE to same sized integral type.
(fold_convert_loc): Fix up formatting. Fold conversion of
VECTOR_TYPE to same sized integral type using VIEW_CONVERT_EXPR
instead of NOP_EXPR.
