re PR middle-end/21024 (fold generates a comparison of two operands whose types do not match)
PR middle-end/21024
* builtins.c (expand_builtin_strcat): Convert the result of
strlen to the right type.
* fold-const.c (fold_binary) <PLUS_EXPR>: Use fold_convert to
avoid creating type mismatches.
<GE_EXPR>: Pass op0 and op1 to fold_build2 to avoid creating
type mismatches.
