* Do not select EhPad BB in MachineBlockPlacement when there is regular BB to ↵Amaury Sechet2016-04-071-52/+0
| | | | | | | | | | | | | | | | | schedule Summary: EHPad BB are not entered the classic way and therefor do not need to be placed after their predecessors. This patch make sure EHPad BB are not chosen amongst successors to form chains, and are selected as last resort when selecting the best candidate. EHPad are scheduled in reverse probability order in order to have them flow into each others naturally.

| | | | | | | | | | | | | | http://reviews.llvm.org/D18562 A large number of testcases has been modified so they pass after this test. One testcase is deleted, because I realized even after undoing the original change that was committed with this testcase, the testcase still passes. So I removed it. The change to one other testcase (test/CodeGen/PowerPC/pr25802.ll) is an arbitrary change to keep it passing. Given the original intention of the testcase, and the fact that fixing it will require some time to change the testcase, we concluded that this quick change will be enough. llvm-svn: 265683
