New Revision: 59747

URL: http://llvm.org/viewvc/llvm-project?rev=59747&view=rev
Log:
Treat mid-block labels the same as terminators when building the
MachineInstr scheduling DAG, meaning they implicitly depend on all
preceding defs. This fixes Benchmarks/Shootout-C++/except and
Regression/C++/EH/simple_rethrow in
  -relocation-model=pic -disable-post-RA-scheduler=false
mode.
