The damage done by physreg coalescing only depends on the number of instructions the extended physreg live range covers. This fixes PR9438. The heuristic is still luck-based, and physreg coalescing really should be disabled completely. We need a register allocator with better hinting support before that is possible. Convert a test to FileCheck and force spilling by inserting an extra call. The previous spilling behavior was dependent on misguided physreg coalescing decisions. llvm-svn: 127351
