Thanks! Looks fixed - testing with r298997:

$ ./opt -slp-vectorizer  31879.ll -S
; ModuleID = '31879.ll'
source_filename = "31879.ll"

define float @f(<2 x float> %x) {
  %1 = fmul <2 x float> %x, %x
  %2 = extractelement <2 x float> %1, i32 0
  %3 = extractelement <2 x float> %1, i32 1
  %add = fadd float %2, %3
  ret float %add
}
