  Log Message:
  -----------
  [SLP] "Normal" instructions should not go between PHI and Lading pad

Currently, SLP can insert "shuffle" instruction beween PHI and Landing pad instruction. The problem is demonstrated by LIT test. The solution is to adjust insertion point once we are done with PHI generation.
