it isn't yet in TOT).

47529c9ac6 Move verbose asm instruction comments to using MCStreamer.
The major win of this is that the code is simpler and they 
print on the same line as the instruction again:

        movl    96(%esp), %eax          ## 4-byte Reload
        cmpl    92(%esp), %eax          ## 4-byte Folded Reload

a2c2f1ae84 Adds a JIT based exception handling example to the examples directory.
Both zero cost example domain specific, and C++ foreign exception handling are 
shown. The example's documentation fully explains how to run the example.

Notes:

1)   The code uses an extremely simple type info model.
2)   Only a single landing pad is used per unwind edge 
     (one call to llvm.eh.selector)
3)   llvm.eh.selector support for filter arguments is not given.
4)   llvm.eh.typeid.for is not used.
5)   Forced unwind behavior is not supported.
6)   Very little if any error handling is given.
7)   __attribute__((__aligned__)) is used.
8)   The code uses parts from the llvm compiler-rt project and
     the llvm Kaleidoscope example.
9)   The code has not been ported or tested on WINDOWS.
10)  The code was not tested with a cmake build.
11)  The code was tested for a debug build on 32bit X86 CentOS LINUX, 
     and both a debug and release build on OS X 10.6.2 (64bit).
