Parsing and sema analysis (without support for array sections in arguments) for 'depend' clause (used in 'task' directive, OpenMP 4.0).

Added parsing, sema analysis and codegen for '#pragma omp taskgroup' directive (OpenMP 4.0).
The code for directive is generated the following way:
#pragma omp taskgroup
<body>
void __kmpc_taskgroup(<loc>, thread_id);
<body>
void __kmpc_end_taskgroup(<loc>, thread_id);

Based on previous discussion on the mailing list, clang currently lacks support
for C99 partial re-initialization behavior:
Reference: http://lists.cs.uiuc.edu/pipermail/cfe-dev/2013-April/029188.html
Reference: http://www.open-std.org/jtc1/sc22/wg14/www/docs/dr_253.htm
This patch attempts to fix this problem.
Given the following code snippet,
struct P1 { char x[6]; };
struct LP1 { struct P1 p1; };
struct LP1 l = { .p1 = { "foo" }, .p1.x[2] = 'x' };
// this example is adapted from the example for "struct fred x[]" in DR-253;
// currently clang produces in l: { "\0\0x" },
// whereas gcc 4.8 produces { "fox" };
// with this fix, clang will also produce: { "fox" };

Allows StmtPrinter to print old style field designators in
initializers, fixing an issue where we would print the following
invalid code:
struct A a = {b: = 3, .c = 4};

A LambdaCapture does not have sufficient information
to correctly determine whether it is an init-capture or not.
Doing so requires knowledge held in the LambdaExpr itself.
It the case of a nested capture of an init-capture it is not
sufficient to check (as LambdaCapture::isInitCapture did)
whether the associated VarDecl was from an init-capture.
This patch moves isInitCapture to LambdaExpr and updates
Capture->isInitCapture() to Lambda->isInitCapture(Capture).

StmtPrinter assumed that the first template arg was the pack and
attempted to iterate it. However, the GNU extension (which is really
just N3599), has two template arguments. In this case, the second
argument is the pack containing the string contents.
Handle this by desugaring the call to the explicit operator.
For example:
"qux" _zombocom will be shown as
operator "" _zombocom<char, 'q', 'u', 'x'>() in diagnostics and AST
dumps.
N.B. It is actually impossible to render the arguments back to the
source form without storing more information in the AST. For example,
we cannot tell if the user wrote u8"qux" or "qux". We also lose
fidelity when it comes to non-char types for this exact reason (e.g. it
is hard to render a list of wchar_t back to something that can be
printed to the screen even if you don't have to consider surrogate
pairs).
This fixes PR23120.

initializer of the form {x}, where x is of type C or a type derived from C,
perform *non-list* initialization of the entity from x, but create a
CXXConstructExpr that knows that we used list-initialization syntax.
Plus some fixes to ensure we mangle correctly in this and related cases.

list-initialization that gets converted to some form other than an
InitListExpr. CXXTemporaryObjectExpr is a special case here, because it
represents a fused CXXFunctionalCastExpr + CXXConstructExpr. That, in
itself, is probably a design error...

This is a new form of expression of the form:
(expr op ... op expr)
where one of the exprs is a parameter pack. It expands into
(expr1 op (expr2onwards op ... op expr))
(and likewise if the pack is on the right). The non-pack operand can be
omitted; in that case, an empty pack gives a fallback value or an error,
depending on the operator.
