This makes the behavior of this routine consistent between libc routines

James Molloy and the inconsistency doesn't seem intentional and likely
is due to intrinsic calls not being modelled in the call graph analyses.

[Sema] More changes to fix Objective-C fallout from r249995.
This is a follow-up to PR26085. That was fixed in r257710 but the testcase
there was incomplete. There is a related issue where the overload resolution
for Objective-C incorrectly picks a method that is not valid without a
bridge cast. The call to Sema::CheckSingleAssignmentConstraints that was
added to SemaOverload.cpp's IsStandardConversion() function does not catch
that case and reports that the method is Compatible even when it is not.
The root cause here is that various Objective-C-related functions in Sema
do not consistently return a value to indicate whether there was an error.
This was fine in the past because they would report diagnostics when needed,
but r257710 changed them to suppress reporting diagnostics when checking
during overload resolution.
This patch adds a new ACR_error result to the ARCConversionResult enum and
updates Sema::CheckObjCARCConversion to return that value when there is an
error. Most of the calls to that function do not check the return value,
so adding this new result does not affect them. The one exception is in
SemaCast.cpp where it specifically checks for ACR_unbridged, so that is
also OK. The call in Sema::CheckSingleAssignmentConstraints can then check
for an ACR_okay result and identify assignments as Incompatible. To
preserve the existing behavior, it only changes the return value to
Incompatible when the new Diagnose argument (from r257710) is false.
Similarly, the CheckObjCBridgeRelatedConversions and
ConversionToObjCStringLiteralCheck need to identify when an assignment is
Incompatible. Those functions already return appropriate values but they
need some fixes related to the new Diagnose argument.

Disable recognition of "using" declarations at translation-unit level.
Currently CountDeclLevels uses the ASTs which have no distinction between
separate translation units. If one .o file has a "using" declaration at
translation unit level, that "using" declaration will be in the same translation
unit as functions from other .o files in the same module. This leads to
erroneous name conflicts as the CountDeclLevels-based function filtering logic
accepts too many fucntions.
In the future we will identify the translation units for top-level Decls more
reliably and restore that functionality. There's a TODO to that effect in the
code.

ELF: Add wildcard pattern matching to SECTIONS linker script command.
Each rule in SECTIONS commands is something like ".foo *(.baz.*)",
which instructs the linker to collect all sections whose name matches
".baz.*" from all files and put them into .foo section.
Previously, we didn't recognize the wildcard character. This patch
adds that feature.
Performance impact is a bit concerning because a linker script can
contain hundreds of SECTIONS rules, and doing pattern matching against
each rule would be too expensive. We could merge all patterns into
single DFA so that it takes O(n) to the input size. However, it is
probably too much at this moment -- we don't know whether the
performance of pattern matching matters or not. So I chose to
implement the simplest algorithm in this patch. I hope this simple
pattern matcher is sufficient.

[CMake] Improve the clang order-file generation workflow
Summary:
This commit re-lands r259862. The underlying cause of the build breakage was an incorrectly written capabilities test. In tools/Driver/CMakeLists.txt I was attempting to check if a linker flag worked, the test was passing it to the compiler, not the linker. CMake doesn't have a linker test, so we have a hand-rolled one.
Original Patch Review: http://reviews.llvm.org/D16896
Original Summary:
With this change generating clang order files using dtrace uses the following workflow:
cmake <whatever options you want>
ninja generate-order-file
ninja clang
This patch works by setting a default path to the order file (which can be overridden by the user). If the order file doesn't exist during configuration CMake will create an empty one.
CMake then ties up the dependencies between the clang link job and the order file, and generate-order-file overwrites CLANG_ORDER_FILE with the new order file.

IRInterpreter now recognizes expressions with constants it doesn't handle.
If an instruction has a constant that IRInterpreter doesn't know how to deal
with (say, an array constant, because we can't materialize it to APInt) then we
used to ignore that and only fail during expression execution. This is annoying
because if IRInterpreter had just returned false from CanInterpret(), the JIT
would have been used.
Now the IRInterpreter checks constants as part of CanInterpret(), so this should
hopefully no longer be an issue.

Centralized symbol lookup in IRExecutionUnit, and fixed the code model.
I'm preparing to remove symbol lookup from IRForTarget, where it constitutes a
dreadful hack working around no-longer-existing JIT bugs. Thanks to our
contributors, IRForTarget has a lot of smarts that IRExecutionUnit doesn't have,
so I've cleaned them up a bit and moved them over to IRExecutionUnit.
Also for historical reasons, IRExecutionUnit used the "Small" code model on non-
ELF platforms (namely, OS X). That's no longer necessary, and we can use the
same code model as everyone else on OS X. I've fixed that.
