Updating the diagnostics in the launch_bounds test since they have been improved in that case. Adding a test for nonnull since it has little test coverage, but has truly variadic arguments.

Clang forgot that '++s.m' was a bitfield l-value and permit it's address
to be taken; this would crash at CodeGen-time.
Instead, propagate the object-kind when we see the prefix
increment/decrement.
This fixes PR20496.

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.

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

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.

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.

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.

r197490 changed the behavior of LIBRARY_PATH to try to match GCC's behavior
for cross compilers and make clang work better on "bare metal" targets.
Unfortunately that change is breaking a number of MacPorts projects because
the LIBRARY_PATH environment variable is being ignored when compiling on a
64-bit host for a 32-bit target. Because the host and target architectures
differ, isCrossCompiling returns true. This does not make sense for Darwin,
where multiple architectures are supported natively via "fat" Mach-O slices
and where development is generally done against SDKs regardless. This patch
fixes the problem by overriding isCrossCompiling to return false for Darwin
toolchains.

The -mstrict-align option was originally added in r167619 as a target-
independent option. It was then changed in r167623 to be implemented with an
ARM-specific backend option, even though the code remained in the
target-independent Clang::ConstructJob function. This means that if you used
the -mstrict-align option with a non-ARM target, you would still get the
-arm-strict-align option getting passed to the backend, which was harmless
but gross. The driver option was then replaced by the GCC-compatible
-m[no-]unaligned-access option (r189175) and modified to work with AArch64
(r208075). However, in the process, the help text for -mstrict-align was
incorrectly changed to show it as only being supported for AArch64. Even worse,
the logic for handling these options together with -mkernel was wrong for
AArch64, where -mkernel does not currently imply strict alignment.
This patch fixes up all of those things. Besides the obvious change to the
option help text, it moves the logic into the ARM and AArch64-specific parts
of the driver, so that the option will be correctly ignored for non-ARM
targets. <rdar://problem/17823697>

This isn't nearly as elaborate as the GCC inline asm which emits an
array of source locations, but it's very, very hard to trigger backend
diagnostics in MS inline asm because we parse it up front with good
source information, unlike GCC inline asm.
Currently I can trigger a "inline assembly requires more registers than
available" diagnostic with this code:
void foo();
void bar() {
__asm pusha
__asm call foo
__asm popa
}
However, if I committed that as a test case, I would have to remove it
once I fix PR20052.
