I had reverted this before the holiday week because a problem was reported with a related change (D137140 - scalable vector known bits in DAG). I had initially confused the two patches, and then decided to leave this reverted out an abundance of caution. Now that we're through the holiday week, reapplying.
I also roled in fixes for several post commit review comments that hadn't landed with the original change.
Original commit message
This is a continuation of the series of patches adding lane wise support for scalable vectors in various knownbit-esq routines.
The basic idea here is that we track a single lane for scalable vectors which corresponds to an unknown number of lanes at runtime. This is enough for us to perform lane wise reasoning on many arithmetic operations.

This reverts commits 3fb08d14a63f5f745d3fec2b5f6ffef4cf0a398c and f8c63a7fbf50fb5883bd566c7539d0ac18c7700f.
There was a "timeout for a Halide Hexagon test" reported. Revert until investigation complete.

These tests were introduced in D109809 which I pushed on behalf of
@tangxingxin1008. I must have not understood the correct arcanist
workflow for this and as such may have locally tested a stale build.
This patch fixes the issue by re-running update_llc_test_checks.py on
all four tests.
Fixed the vector type issue that where we used getVectorNumElements()
should be replaced by getVectorElementCount() when lowering these
intrinsics.
This is similar to D94149
