in general (such an atomic has boolean representation) and
specifically for IR generation of __c11_atomic_init. The latter also
means actually using initialization semantics for this initialization,
rather than just creating a store.
On a related note, make sure we actually put in non-atomic-to-atomic
conversions when performing an implicit conversion sequence. IR
generation is far too kind here, but we still want the ASTs to make
sense.

types. The second and third conversions in the sequence are based on
the conversion for the underlying type, so that we get sensible
overloading behavior for, e.g., _Atomic(int) vs. _Atomic(float).
As part of this, actually implement the lvalue-to-rvalue conversion
for atomic types. There is probably a pile of code in SemaExpr that
can now be deleted, but I haven't tracked it down yet.

CompilerInstance::setCodeCompletionConsumer instead, in order to change
the SkipFunctionBodies flag accordingly. Also fixed
setCodeCompletionConsumer to take a reset() to null into account.

turns out that it's actually needed for C++ modules support. Since simplifying
it didn't cause any test failures, I'll add a test for it.

This is not quite sufficient for libstdc++'s <atomic>: we still need
__atomic_test_and_set and __atomic_clear, and may need a more complete
__atomic_is_lock_free implementation.
We are also missing an implementation of __atomic_always_lock_free,
__atomic_nand_fetch, and __atomic_fetch_nand, but those aren't needed
for libstdc++.

get the diagnostic category name from a serialized diagnostic when the version of libclang used
to read the diagnostic file is newer than the clang that emitted the diagnostic file.

As per Jordy's review. Creating a symbol here is more flexible; however
I could not come up with an example where it was needed. (What
constrains can be added on of the symbol constrained to 0?)

to get at the parameters (and their types) of a function or objc method cursor.

In passing, fix LanguageExtensions to note that C11 and C++11 are no longer
"upcoming standards" but are now actually standardized.

PCH failed to load).
Also honor displayDiagnostics in clang_indexSourceFile().

(Applied changes to CStringAPI, Malloc, and Taint.)
This might almost never happen, but we should not crash even if it does.
This fixes a crash on the internal analyzer buildbot, where postgresql's
configure was redefining memmove (radar://11219852).
