[Bug objc/31281] New: ICE on ObjC try-catch blocks

[stuart at apple dot com]

The 4.2 ObjC compiler ICEs on this (nonsensically reduced) testcase.  Compile
with -O2:

int f(unsigned int i)
{
  @try { } @catch(id) { }
  for (;;)
    for (;;)
      @try {
        if (i)
          break;
      } @catch(id) { }
}

The 4.0 compiler does not ICE with this testcase.

This works for me on the trunk on powerpc-linux-gnu with the GNU runtime and
next runtime.
