Warren Ristow 230c8c56f2 [Reassociate] Cleanup minor missed optimizations 
In analyzing issue #56483, it was noticed that running `opt` with
`-reassociate` was missing some minor optimizations. For example,
there were cases where the running `opt` on IR with floating-point
instructions that have the `fast` flags applied, sometimes resulted in
less efficient code than the input IR (things like dead instructions
left behind, and missed reassociations). These were sometimes noted
in the test-files with TODOs, to investigate further. This commit
fixes some of these problems, removing some TODOs in the process.

FTR, I refer to these as "minor" missed optimizations, because when
running a full clang/llvm compilation, these inefficiencies are not
happening, as other passes clean that residue up. Regardless, having
cleaner IR produced by `opt`, makes assessing the quality of fixes done
in `opt` easier.
