Revert the part of r59145 that changed the comment about
...
virtual registers possibly having multiple kills while still
being defined and killed in the same block. If LiveIntervals
is manually re-run after two-address lowering, it currently
does add extra kills to two-address instructions, but this
is considered a bug.

Move the code that inserts X87 FP_REG_KILL instructions from a

special-purpose hook to a new pass. Also, add check to see if any
x87 virtual registers are used, to avoid doing any work in the
common case that no x87 code is needed.

Simplify SplitVecRes_EXTRACT_SUBVECTOR. This means
...
that it no longer handles non-power-of-two vectors.
However it previously only handled them sometimes,
depending on obscure numerical relationships between
the index and vector type. For example, for a vector
of length 6, it would succeed if and only if the
index was an even multiple of 6. I consider this
more confusing than useful.
