(commit again after fixing the buildbot failures)
This adds various overloads of the following builtins to altivec.h:
vec_neg
vec_nabs
vec_adde
vec_addec
vec_sube
vec_subec
vec_subc
Note that for vec_sub builtins on 32 bit integers, the semantics is similar to
what ISA describes for instructions like vsubecuq that work on quadwords: the
first operand is added to the one's complement of the second operand. (As
opposed to two's complement which I expected).

This commit teaches clang that is has to emit a warning when NULL is passed
as the 'expected' pointer parameter into an atomic compare exchange call.

Summary:
We don't need a side table in ASTContext to hold CXXDefaultArgExprs. The
important part of building the CXXDefaultArgExprs was to ODR use the
default argument expressions, not to make AST nodes. Refactor the code
to only check the default argument, and remove the side table in
ASTContext which wasn't being serialized.

This commit fixes an incorrectly formatted Objective-C block parameter
placeholder in a code completion result. The incorrect parameter had a

Currently, TargetLibraryInfoWrapperPass is inserted by PMBuilder.
However, some passes are inserted manually before the PMBuilder
ones - if any of them happens to use TargetLibraryInfoWrapperPass,
it'll get a default-constructed one, with an unknown target triple.
This happens to InstrProfiling in D21736, breaking it.

https://reviews.llvm.org/D25932 made it so that clang always checks if
libLTO.dylib is present on disk, even if -flto is not being used. The
motivation for that change was that if a dependency happens to contain bitcode,
ld64 will try to load libLTO without -flto explicitly being enabled. However,
the change had the undesirable side effect of warning if libLTO.dylib doesn't
exist even if it isn't needed.
Change things so that -lto_library is always passes, independent of if it
exists or not. ld64 only looks at this flag if it uses LTO. If the dylib
exists, all is well. If it doesn't, and LTO is not being used, all is well too.
If ld64 does end up using LTO and the dylib does not exist, ld64 will print
something like
ld: could not process llvm bitcode object file, because foo/libLTO.dylib could not be loaded file 'test.o' for architecture x86_64

Summary:
The new error information contains the type of error (e.g. overlap or bad file path)
and the replacement(s) that is causing the error. This enables us to resolve some errors.
For example, for insertion at the same location conflict, we need to know the
existing replacement which conflicts with the new replacement in order to calculate
the new position to be insert before/after the existing replacement (for merging).

Because in case of unions we currently default-bind compound values in the

This is needed because whether the constructor is deleted can control whether
we pass structs by value directly.
To fix this properly we probably want a more direct way for CodeGen to ask
whether the constructor was deleted.

of a method that was declared in an invalid interface
This commit fixes an infinite loop that occurs when clang tries to iterate over
redeclaration of a method that was declared in an invalid @interface. The
existing validity checks don't catch this as that @interface is a duplicate of
a previously declared valid @interface declaration, so we have to verify that
the found redeclaration is in a valid declaration context.

This commit adds a new predefined macro named __OBJC_BOOL_IS_BOOL that describes
the Objective-C boolean type: its value is zero if the Objective-C boolean uses
the signed character type, otherwise its value is one as the Objective-C boolean
uses the builtin boolean type.

with __unknown_anytype return type.
When the following code is compiled, Sema infers that the type of
__unknown_anytype is double:
extern __unknown_anytype func();
double *d = (double*)&func();
This triggers an assert in CodeGenFunction::EmitCallExprLValue because
it doesn't expect to see a call to a function with a non-reference
scalar return type.
This commit prevents the assert by making VisitUnaryAddrOf error out if
the address-of operator is applied to a call to a function with
__unknown_anytype return type.

Summary:
This is a simple sema check patch for arguments of `__builtin_arm_rsr` and the related builtins, which currently do not allow special registers with indexes >7.
Some of the possible register name formats these builtins accept are:
```
{c}p<coprocessor>:<op1>:c<CRn>:c<CRm>:<op2>
```
```
o0:op1:CRn:CRm:op2
```
where `op1` / `op2` are integers in the range [0, 7] and `CRn` / `CRm` are integers in the range [0, 15].
The current sema check does not allow `CRn` > 7 and accepts `op2` up to 15.
