Subzero: More asm-verbose fixes.

It turns out that code deleted in 9a05aea88a8d9484d5f0ea1f2eabf52ee5a3647f actually had a legitimate purpose, so it is added back, this time with more extensive comments justifying it.

Also, takes the instruction's IsDestNonKillable flag into account when updating the live register usage count (along with extra comments on why that is necessary).

Furthermore, removes an unnecessary assert that otherwise fails when --asm-verbose is used with --filetype=iasm or --filetype-obj.

BUG= none
