MS ABI: Consider alignment attributes on typedefs for layout

The MS ABI has a notion of 'required alignment' for fields; this
alignment supercedes pragma pack directives.

MSVC takes into account alignment attributes on typedefs when
determining whether or not a field has a certain required alignment.

Do the same in clang by tracking whether or not we saw such an attribute
when calculating the type's bitwidth and alignment.

This fixes PR20418.

MS ABI: Mangle alias templates used as template-template arguments

A templated using declaration may be used as a template-template
argument.

Unfortunately, the VS "14" chooses '?' as the sole marker for the
argument.  This is problematic because it presupposes the possibility of
using more than one template-aliases as arguments to the same template.

This fixes PR20047.

Fix some cases of incorrect handling of lifetime extended temporaries.

MaterializeTemporaryExpr already contains information about the lifetime
of the temporary; if the lifetime is not the full statement, we do not
want to emit a destructor at the end of the full statement for it.

AST: Simplify some code

Iterator invalidation issues already force us to do one lookup and one
insert.
Don't use the particular bit-pattern of the 'Align' field to determine
whether or not we have already inserted into the TypeInfo DenseMap;
instead ask for an iterator to the TypeInfo entry.

Fix OpenCL/SPIR kernel_arg_type metadata node

This fixes a bug where kernel_arg_type was always changing 'unsigned ' to 'u'
for any parameter type, including non-canonical types.

Example:
  typedef unsigned int myunsignedint;
would report:
  "myunt"

Add OpenCL/SPIR kernel_arg_base_type metadata node

As defined in the SPIR 1.2 specification, this node behaves similarly to
kernel_arg_type but will print the underlying type name, e.g., without
typedefs.

Example:
  typedef unsigned int myunsignedint;
would report:
  'myunsignedint' in the kernel_arg_type node
  'uint' in the kernel_arg_base_type node

Add a state variable to the loop hint attribute.

This patch is necessary to support constant expressions which replaces the integer value in the loop hint attribute with an expression. The integer value was also storing the pragma’s state for options like vectorize(enable/disable) and the pragma unroll and nounroll directive. The state variable is introduced to hold the state of those options/pragmas. This moves the validation of the state (keywords) from SemaStmtAttr handler to the loop hint annotation token handler.
