section for x86_64 and i386 targets on Darwin systems. Currently only the compact unwind encoding for normal frame-using functions is supported but it will be easy handle frameless functions when I have a bit more free time to test it. The LSDA and personality routines for functions are also retrieved correctly for functions from the compact unwind section. This new code is very fresh -- it passes the lldb testsuite and I've done by-hand inspection of many functions and am getting correct behavior for all of them. There may need to be some bug fixing over the next couple weeks as I exercise and test it further. But I think it's fine right now so I'm committing it. <rdar://problem/13220837> llvm-svn: 223625
