Fix PR15355 - Clear 'mayStore' flag when loading from the atomic variable before the spin loop - Clear kill flag from one use to multiple use in registers forming the address to that atomic variable - don't use a physical register as live-in register in BB (neither entry nor landing pad.) by copying it into virtual register (patch by Cameron Zwarich) llvm-svn: 176538
