Encapsulate PassManager debug flags to avoid static init and cxa_exit.
This puts all the global PassManager debugging flags, like -print-after-all and -time-passes, behind a managed static. This eliminates their static initializers and, more importantly, exit-time destructors. The only behavioral change I anticipate is that tools need to initialize the PassManager before parsing the command line in order to export these options, which makes sense. Tools that already initialize the standard passes (opt/llc) don't need to do anything new. git-svn-id: 91177308-0d34-0410-b5e6-96231b3b80d8
