Extract spill cost calculation to a new method, and use definePhysReg() to clear
...
out aliases when allocating. Clean up allocVirtReg().
Use calcSpillCost() to allow more aggressive hinting. Now the hint is always
taken unless blocked by a reserved register. This leads to more coalescing,
lower register pressure, and less spilling.

Pick the correct personality function based on the language. This prevents link failures when C/ObjC code uses __attribute__((cleanup())) (previously this was inserting references to two libstc++ symbols; the personality function and the __terminate() function).
...
This is still probably wrong for Objective-C++ and adds a couple of lines in CGException that should probably be in the CGObjCRuntime subclass. The personality function is now only looked up in one place in CGException though, so this should be easier to fix in the future.

When initializing thread-safe statics, put the call to

__cxa_guard_abort along the exceptional edge into (in effect) a nested
"try" that rethrows after aborting. Fixes PR7144 and the remaining
Boost.ProgramOptions failures, along with the regressions that r103880
caused.
The crucial difference between this and r103880 is that we now follow
LLVM's little dance with the llvm.eh.exception and llvm.eh.selector
calls, then use _Unwind_Resume_or_Rethrow to rethrow.
