    expand: Use the correct mode for store flags for popcount [PR116480]

    When expanding popcount used for equal to 1 (or rather
__builtin_stdc_has_single_bit),
    the wrong mode was bsing used for the mode of the store flags. We were
using the mode
    of the argument to popcount but since popcount's return value is always
int, the mode
    of the expansion here should have been the mode of the return type rater
than the argument.

    Built and tested on aarch64-linux-gnu with no regressions.
    Also bootstrapped and tested on x86_64-linux-gnu.
