[PATCH 2/2] simplify kill_insn() of unops and unop-ish instructions

[Luc Van Oostenryck <luc.vanoostenryck@gmail.com>]

In instructions, the first pseudo operands exist under different
names (.src1, .src, .cond, .phi_src) all aliased to each other.

Use this to simplify unops and others instructions with a single
pseudo operand.
