b121bfcc22 Version N of the llvm_unreachable patch: VC++ doesn't recognize that abort() 
doesn't return, so just go back to using the old runtime function instead
of trying to use abort() when __builtin_unreachable (or an equivalent) isn't
supported.

2f9a9ed785 Make llvm_unreachable evaluate to __builtin_unreachable() in -Asserts 
builds, which was the apparent consensus of PR8973 and llvmdev.

fatal error handlers which automatically get unregistered at the end
of a scope.

66b856683f Make it easier to use the llvm_unreachable and DEBUG macros without "using 
namespace llvm" by qualifying their implementations with ::llvm::.

7b068610eb Make NORETURN working with MSVC. MSVC only accepts NORETURN in front of the 
decl so move it there. GCC accepts it both in front and after decls.

something.

c23197a26f llvm_unreachable->llvm_unreachable(0), LLVM_UNREACHABLE->llvm_unreachable. 
This adds location info for all llvm_unreachable calls (which is a macro now) in
!NDEBUG builds.
In NDEBUG builds location info and the message is off (it only prints
"UREACHABLE executed").

93990d775e After converting assert(0) to LLVM_UNREACHABLE we lost file/line location. 
Fix by making the LLVM_UNREACHABLE pass __FILE__ and __LINE__ to
llvm_unreachable.

c25e7581b9 assert(0) -> LLVM_UNREACHABLE. 
Make llvm_unreachable take an optional string, thus moving the cerr<< out of
line.
LLVM_UNREACHABLE is now a simple wrapper that makes the message go away for
NDEBUG builds.

31e2466f15 Introduce new error handling API. 
This will replace exit()/abort() style error handling with an API
that allows clients to register custom error handling hooks.
The default is to call exit(1) when no error handler is provided.
