Message:

DFG relies on returning a struct in registers
​https://bugs.webkit.org/show_bug.cgi?id=74527

Reviewed by Geoff Garen.

This will not work on all platforms. Returning a uint64_t will more reliably achieve
what we want, on 32-bit platforms (on 64-bit, stick with the struct return).
