We can only do the optimization if the source *is* SSA.

Squashed with commit:
i965/fs: Remove the inline pack_double_2x32 optimization
It's broken in a number of ways. In particular, a bunch of the
conditions are backwards so it doesn't actually detect what it's
supposed to detect. Since it's been broken, it hasn't actually been
helping anything so just deleting it isn't a regression.
This (and removing another optimization) were done on master in commit
b07381161777ba5d5f4a1d713f7655bcaede4139.
