5a996fc0fc Now that LLVM CodeGen can handle the generic variations a bit better, 
get rid of a few more clang vector builtins.

insert/extract; the relevant instructions are defined to take only an

4be99ff767 ABI handling: Fix nasty thinko where IRgen could generate an out-of-bounds read 
when generating a coercion for ABI handling purposes.
 - This may only manifest itself when building at -O0, but the practical effect
   is that other arguments may get clobbered.

4b665ebb01 Add clang-cc support for -disable-llvm-optzns. 
- Avoids running any LLVM optimizations, even at -O2, etc., while still keeping
   any language changes these optimizations imply.

cb9d07caeb Add support for __builtin_unwind_init. 
Also, committing an #if 0'ed __builtin_setjmp and __builtin_longjmp 
implementation I've had sitting in my tree for a while.  I haven't 
enabled it because the LLVM backend support isn't complete yet.

1518b64ddc When trying to pass an argument on the stack, assume LLVM will do the right 
thing for non-aggregate types.
 - Otherwise we unnecessarily pin values to the stack and currently end up
   triggering a backend bug in one case.

 - This loose cooperation with LLVM to implement the ABI is pretty ugly.

aed08f9929 Fixup blocks codegen for { __block i; i = rhs(); }, we want the rhs 
evaluated first.  This can also improve codegen just a bit as we might
have another register to play with for the evaluation of the rhs.

ffdb8439d7 ABI handling: Fix invalid assertion, it is possible for a valid 
coercion to be specified which truncates padding bits. It would be
nice to still have the assert, but we don't have any API call for the
unpadding size of a type yet.

5b9241b2a6 Fix the atomics sema code to convert operands to the argument types 
of the underlying _N builtin, not the the type of the pointee of the
actual type.  This ensures that atomics involving pointers end up
using the correct integer type when they are resolved, avoiding
aborts in codegen.
