The MachO toolchain has an isTargetIOSBased method, but it isn't
virtual so it isn't very meaningful to call it. After thinking about
this, I guess that putting this logic in the MachO class is a bit of a
layering violation anyway. Do this more like how we handle
AddLinkRuntimeLibArgs instead.

XFAIL TestCModules - use of undeclared identifier 'MIN'

to use the information in the module rather than TargetOptions.
We've had and clang has used the use-soft-float attribute for some
time now so have the backends set a subtarget feature based on
a particular function now that subtargets are created based on
functions and function attributes.
For the one middle end soft float check go ahead and create
an overloadable TargetLowering::useSoftFloat function that
just checks the TargetSubtargetInfo in all cases.
Also remove the command line option that hard codes whether or
not soft-float is set by using the attribute for all of the
target specific test cases - for the generic just go ahead and
add the attribute in the one case that showed up.

This is a very minor change.
Just reshuffle the elements of the log filename so that the test name
comes before the arch/compiler
Before:
Failure-x86_64-clang-TestCModules.CModulesTestCase.test_expr_with_dwarf.log
After:
Failure-TestCModules.CModulesTestCase.test_expr_with_dwarf-x86_64-clang.log
This way, results are grouped by test name, not by arch. I think this
is much more useful.

Compiler-rt's Profiling library isn't part of the stdlib, so -nostdlib
shouldn't prevent it from being linked. This makes Darwin behave like
other toolchains, and link in the profile runtime irrespective of
-nostdlib, since the resulting program can't be run unless you link
this.
I've also added a test to show that other toolchains already behave
like this.

Empty assembly string will not introduce assembly code in the output
binary and it is often used as a trick in the header to disable

Summary:
The original code inserted new instructions by following a
Create->Remove->ReInsert flow. This patch removes the unnecessary
Remove->ReInsert part by setting up the InsertPoint correctly at the
very beginning. This change does not introduce any functionality change.

This fixes another miscompile introduced by r235232: when there was a
dependency on the memcpy destination other than the memset, we would
ignore it, because we only looked at the source dependency.
It was a mistake to use SrcDepInfo. Instead, just use DepInfo.

This is necessary in order to allow the use of a constexpr member function, or

The TargetRegistry is just a namespace-like class, instantiated in one
place to use a range-based for loop. Instead, expose access to the
registry via a range-based 'targets()' function instead. This makes most
uses a bit awkward/more verbose - but eventually we should just add a
range-based find_if function which will streamline these functions. I'm
happy to mkae them a bit awkward in the interim as encouragement to
improve the algorithms in time.

Also, change code in tablegen which printed a message and then called
"exit(1)" to use PrintFatalError, instead.
This fixes instances where an empty output file was left behind after
a failed tablegen invocation, which would confuse subsequent ninja
runs into not attempting to rebuild.

Summary:
TargetList::CreateTargetInternal() will only select the current Platform. A previous patch always sets platform_sp to the current Platform, so a check later to see if platform_sp was not defined always failed, and the current Platform was used. This patch removes that check, so if the current Platform is not compatible with the target architecture, CreateTargetInternal() will call Platform::GetPlatformForArchitecture() to select a compatible Platform.
Vince, remote linux tests (Ubuntu -> remote Ubuntu) pass the same with and without this patch.

Summary: The Linux Platform shouldn't care about the Vendor field in the Triple. Currently it allows a value of "PC", or "unknown" if LLDB was built on Linux. This patch removes that check, so the Vendor field isn't touched. This will allow the Linux Platform to be created when using a Triple of *-*-Linux.

1. llvm-as/llvm-dis tools do not check for input filename length.
2. llvm-dis does not verify the `Streamer` variable against `nullptr` properly, so the `M` variable could be uninitialized (e.g. if the input file does not exist) leading to null dref.

Summary:
AsmLabel is heavily used in system level and firmware to redirect
function and access platform specific labels. They are also extensively
used in system headers which makes this option unusable for many
users. Since AsmLabel doesn't introduce any assembly code into the
output binary, it shouldn't be considered as inline-asm.

This is a less ambitious version of:

http://reviews.llvm.org/rL236600
because it caused memory corruption that wasn't related to FMF
but was actually due to making nodes with 2 operands derive from a
plain SDNode rather than a BinarySDNode.
This patch adds the minimum plumbing necessary to use IR-level
fast-math-flags (FMF) in the backend without actually using
them for anything yet. This is a follow-on to:
http://reviews.llvm.org/rL235997
...which split the existing nsw / nuw / exact flags and FMF
into their own struct.
