[Bug objc/32530] New: @try/@throw/@catch/@finally usage without -fexeceptions compiles without warning/error

[nmiell at comcast dot net]

Test case:

$ cat except.m
#include <objc/Object.h>

@interface E: Object
@end
@implementation E
@end

int main(int argc, char* argv[])
{
        @try {
                @throw [E new];
        } @catch(E *e) {
        }
        return 0;
}
$ gcc -Wall -O2 -g -lobjc except.m -o except
$ ./except
Aborted (core dumped)
$

No warnings or errors a compile time and a completely unexpected runtime
failure.
