Revert two swscale commits.
...
Revert "swscale: update context offsets after removal of AlpMmxFilter."
(commit a95e3fa90b
)
and
Revert "swscale: Remove some write-only variables related to alpha handling."
(commit 9d03cb9fc5
).
They broke alpha handling - it's the evil inline asm that still uses that
variable, so it's not truely write-only.

They were introduced in an earlier commit that introduced use of named

x264asm that I work around by not using named arguments.
