Than McIntosh bb76193a7f cmd/compile: fix buglet in walk convert phase relating to convF32/64
The helper function used by the compiler's walk phase to determine
whether a param can be passed in a single float register wasn't quite
correct (didn't allow for the possibility of struct with two fields,
first zero size and second float). Fix up the helper to take this
case into account.

Updates #40724.
