[OpenMP] Fix mapping of scalars for combined directives
Combined directives like 'target parallel' have two captured statements.
Sema has to check the right one from the right direction.
Previously, Sema::IsOpenMPCapturedByRef would return false for mapped
scalars on combined directives. This results in a wrong signature of
the outlined function which triggers an assertion:
void llvm::CallInst::init(llvm::FunctionType *, llvm::Value *, ArrayRef<llvm::Value *>, ArrayRef<OperandBundleDef>, const llvm::Twine &): Assertion `(i >= FTy->getNumParams() || FTy->getParamType(i) == Args[i]->getType()) && "Calling a function with a bad signature!"' failed.

Summary:
This patch introduces a few extra BraceWrapping options, similar to
`SplitEmptyFunction`, to allow merging empty 'record' bodies (e.g.
class, struct, union and namespace):
* SplitEmptyClass
* SplitEmptyStruct
* SplitEmptyUnion
* SplitEmptyNamespace
The `SplitEmptyFunction` option name has also been simplified/
shortened (from `SplitEmptyFunctionBody`).
These options are helpful when the correspond AfterXXX option is
enabled, to allow merging the empty record:
class Foo
{};
In addition, this fixes an unexpected merging of short records, when
the AfterXXXX options are used, which caused to be formatted like
this:
class Foo
{ void Foo(); };
This is now properly formatted as:
class Foo
{
void Foo();
};

clang-format: Do not binpack initialization lists
Summary:
This patch tries to avoid binpacking when initializing lists/arrays, to allow things like:
static int types[] = {
registerType1(),
registerType2(),
registerType3(),
};
std::map<int, std::string> x = {
{ 0, "foo fjakfjaklf kljj" },
{ 1, "bar fjakfjaklf kljj" },
{ 2, "stuff fjakfjaklf kljj" },
};
This is similar to how dictionnaries are formatted, and actually corresponds to the same conditions: when initializing a container (and not just 'calling' a constructor).
Such formatting involves 2 things:
* Line breaks around the content of the block. This can be forced by adding a comma or comment after the last element
* Elements should not be binpacked
This patch considers the block is an initializer list if it either ends with a comma, or follows an assignment, which seems to provide a sensible approximation.
