8709927af8 Fix a bug in the recent rewrite of the leakdetector that caused all of the

was depending on undefined behavior: the order of destruction of static objects.

e42cde2a14 Now that the lowerinvoke pass inserts calls to llvm.setjmp/llvm.longjmp, some 
hacks can be banished.  Also, this gives us the opportunity to emit special code
for the setjmp/longjmps which alows the elimination of one GCC warning for every
setjmp/longjmp site (which is often THOUSANDS in C++ programs).  Yaay!

588e72db75 Refactor code. Now the intrinsic lowering pass tries to recycle preexisting 
prototypes, even if they don't precisely match what it would prefer to use.
This fixes: CBackend/2004-02-15-PreexistingExternals.llx compiling it into:

  ltmp_0_30 = memcpy(l14_C, 4u, 17);
  ltmp_1_30 = memcpy(((int *)l27_A), ((unsigned )(long)l27_B), ((int )123u));

instead of:

  ltmp_0_30 = memcpy(l14_C, 4u, 17);
  ltmp_1_27 = l43_memcpy(l27_A, l27_B, 123u);

Which does the wrong thing as you could imagine.

cc42d2c3cc A target that doesn't support these intrinsics will still meet spec (the 
intrinsic will always produce zero), but it will behave unexpectedly, so
warn like GCC does.

94f4f8ea10 Make the cwriter use the lowerinvoke pass so that it can either use "disabled exceptions" or 
"expensive exceptions" controlled by an option.  Also refactor and eliminate a bunch of cruft.
This is a temporary solution and causes millions of warnings to pour out of programs that use
exceptions, but it should fix the problem with sparc and the 'write' declaration (PR190).
Subsequent changes will make this stink much less
