[PBQP] Teach PassConfig to tell if the default register allocator is used. This enables targets to adapt their pass pipeline to the register allocator in use. For example, with the AArch64 backend, using PBQP with the cortex-a57, the FPLoadBalancing pass is no longer necessary. llvm-svn: 220321

[AArch64] Reenable the PBQP test now that the leak issue has been fixed. David Blaikie's commits r217563 & r217564, which added shared_ptr to the CostPool have fixed some memory leak issues exposed by the PBQP with coalescing constraints. The sanitizer bot was failing because of those leaks. Now that the leaks are gone, we can reenable the aarch64/pbqp test. llvm-svn: 217580
