This adds the new instructions 'landingpad' and 'resume'.

X86ISD::MEMBARRIER does not require SSE2; it doesn't actually generate any code, and all x86 processors will honor the required semantics.

make the C++stdlib string summary work even if for some reason std::basic_string<char> ends up in the debug info instead of std::string

The numbering of LLVMOpcode is supposed to be stable; revert my earlier change, and append Fence onto the end.

Refactor the rest of the extend instructions to not artificially distinguish
between a rotate of zero and a rotate of any other value. Replace the by-zero
versions with Pat<>'s for ISel.

llvm-svn: 136226

Refactor the SXTB, SXTH, SXTB16, UXTB, UXTH, and UXTB16 instructions to not
have an 'r' and an 'r_rot' version, but just a single version with a rotate
that can be zero. Use plain Pat<>'s for the ISel of the non-rotated version.

- Replace calling -zone with 'nil'. -zone is obsolete in ARC.
- Allow removing retain/release on a static global var.
- Fix assertion hit when scanning for name references outside a NSAutoreleasePool scope.
- Automatically add bridged casts for results of objc method calls and when calling CFRetain, for example:

NSString *s;
CFStringRef ref = [s string];   -> CFStringRef ref = (__bridge CFStringRef)([s string]);
ref = s.string;                 -> ref = (__bridge CFStringRef)(s.string);
ref = [NSString new];           -> ref = (__bridge_retained CFStringRef)([NSString new]);
ref = [s newString];            -> ref = (__bridge_retained CFStringRef)([s newString]);
ref = [[NSString alloc] init];  -> ref = (__bridge_retained CFStringRef)([[NSString alloc] init]);
ref = [[s string] retain];      -> ref = (__bridge_retained CFStringRef)([s string]);
ref = CFRetain(s);              -> ref = (__bridge_retained CFTypeRef)(s);
ref = [s retain];               -> ref = (__bridge_retained CFStringRef)(s);

- Emit migrator error when trying to cast to CF type the result of autorelease/release:
  for

CFStringRef f3() {
  return (CFStringRef)[[[NSString alloc] init] autorelease];
}

emits:

t.m:12:10: error: [rewriter] it is not safe to cast to 'CFStringRef' the result of 'autorelease' message; a __bridge cast may result in a pointer to a destroyed object and a __bridge_retained may leak the object
  return (CFStringRef)[[[NSString alloc] init] autorelease];
         ^            ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
t.m:12:3: note: [rewriter] remove the cast and change return type of function to 'NSString *' to have the object automatically autoreleased
  return (CFStringRef)[[[NSString alloc] init] autorelease];
  ^

- Before changing attributes to weak/unsafe_unretained, check if the backing ivar
  is set to a +1 object, in which case use 'strong' instead.
