[JSC] Move B3ReduceSIMDShuffle to B3ReduceStrength for now
https://bugs.webkit.org/show_bug.cgi?id=309993
rdar://172627278
Reviewed by Justin Michaud.
After 309299@main, we no longer use B3::UseCount in B3ReduceSIMDShuffle.
Then we do not need to have a special path for that. This patch just removes
B3ReduceSIMDShuffle and move them to B3ReduceStrength.
We will add B3ReduceSIMDShuffle when we need to have B3::UseCount for
used-lane analysis. But right now, we are not having these
optimizations.
