[webkit-dev] Proposal: Not supporting x86 w/o SSE2

Technically, many of WebKitGTK+'s distributors require that it not use
SSE2 instructions in 32-bit builds. I am no longer sure which ones. (It
used to be the case for Fedora, for example, but that changed recently.)
In practice, so few people care about these old machines anymore that
such use is unlikely to be noticed by many users. Certain software
(including Firefox and Chromium) has already started to require SSE2
and is broken on these machines, so the requirement is already not
fulfilled by other software. E.g. it is clear that Debian is not
patching Firefox or Chromium to remove the SSE2 instructions.
So times change, and I think we can get away with starting to require
SSE2, if there is a compelling reason to do so. But according to
Filip's review in that bug, we probably don't need to do so right now.
