Alex Crichton 352ee2b186 Move insertlane to ISLE (#3544)
This also fixes a bug where `movsd` was incorrectly used with a memory
operand for `insertlane`, causing it to actually zero the upper bits
instead of preserving them.

Note that the insertlane logic still exists in `lower.rs` because it's
used as a helper for a few other instruction lowerings which aren't
migrated to ISLE yet. This commit also adds a helper in ISLE itself for
those other lowerings to use when they get implemented.

Closes #3216
