Richard Sandiford 1fb5c13e3a Fix Scalarizer insertion point when replacing PHIs with insertelements 
If the Scalarizer scalarized a vector PHI but could not scalarize
all uses of it, it would insert a series of insertelements to reconstruct
the vector PHI value from the scalar ones.  The problem was that it would
emit these insertelements immediately after the PHI, even if there were
other PHIs after it.

The old code only worked for one index operand.  Also handle "inbounds".
