Subject: [PATCH] REGRESSION(274077@main): failure to build on i586 (and likely
 other 32bit arches): static assertion failed: Timer should stay small
 https://bugs.webkit.org/show_bug.cgi?id=271108

Unreviewed build fix. This changes SameSizeOfTimer to ensure it matches
the size of Timer on 32-bit platforms.
