[VectorCombine] fix crashing on match of non-canonical fneg
We can't assume that operand 0 is the negated operand because
the matcher handles "fsub -0.0, X" (and also +0.0 with FMF).
By capturing the extract within the match, we avoid the bug
and make the transform more robust (can't assume that this
pass will only see canonical IR).
