Add option to disable access to the global filesystem namespace.
Systems like FreeBSD's Capsicum and Nuxi CloudABI apply the concept of
capability-based security on the way processes can interact with the
filesystem API. It is no longer possible to interact with the VFS
through calls like open(), unlink(), rename(), etc. Instead, processes
are only allowed to interact with files and directories to which they
have been granted access. The *at() functions can be used for this
purpose.
This change adds a new config switch called
_LIBCPP_HAS_NO_GLOBAL_FILESYSTEM_NAMESPACE. If set, all functionality
that requires the global filesystem namespace will be disabled. More
concretely:
- fstream's open() function will be removed.
- cstdio will no longer pull in fopen(), rename(), etc.
- The test suite's get_temp_file_name() will be removed. This will cause
all tests that use the global filesystem namespace to break, but will
at least make all the other tests run (as get_temp_file_name will not
build anyway).
It is important to mention that this change will make fstream rather
useless on those systems for now. Still, I'd rather not have fstream
disabled entirely, as it is of course possible to come up with an
extension for fstream that would allow access to local filesystem
namespaces (e.g., by adding an openat() member function).

[X86] Fix wrong target specific combine on SETCC nodes.
Part of the folding logic implemented by function 'PerformISDSETCCCombine'
only worked under the assumption that the condition code in input could have
been either SETNE or SETEQ.
Unfortunately that assumption was incorrect, and in some cases the algorithm
ended up incorrectly folding SETCC nodes.
The incorrect folding only affected SETCC dag nodes where:
- one of the operands was a build_vector of all zeroes;
- the other operand was a SIGN_EXTEND from a vector of MVT:i1 elements;
- the condition code was neither SETNE nor SETEQ.
Example:
(setcc (v4i32 (sign_extend v4i1:%A)), (v4i32 VectorOfAllZeroes), setge)
Before this patch, the entire dag node sequence from the example was
incorrectly folded to node %A.
With this patch, the dag node sequence is folded to a
(xor %A, (v4i1 VectorOfAllOnes)).
Added test setcc-combine.ll.

Sema: Don't emit a missing prototype warning for deleted functions.
This is a bit more involved than I anticipated, so here's a breakdown
of the changes:
1. Call ActOnFinishFunctionBody _after_ we parsed =default and
=delete specifiers. Saying that we finished the body before parsing
=default is just wrong. Changing this allows us to use isDefaulted
and isDeleted on a decl in ActOnFinishFunctionBody.
2. Check for -Wmissing-prototypes after we parsed the function body.

Use Sema's PrintingPolicy when diagnosing DeclSpecs.
Sema overrides ASTContext's policy on the first emitted diagnostic
(doesn't matter if it's ignored or not). This means changing the order
of diagnostic emission in Sema suddenly changes the text of diagnostic
emitted from the parser.
In the test case -Wmissing-prototypes (ignored) was the culprit, use
'int main' to suppress that warning so we see when this regresses.
Also move it into Sema/ as it's not testing any C++.

Summary:
The operand flag word for ISD::INLINEASM nodes now contains a 15-bit
memory constraint ID when the operand kind is Kind_Mem. This constraint
ID is a numeric equivalent to the constraint code string and is converted
with a target specific hook in TargetLowering.
This patch maps all memory constraints to InlineAsm::Constraint_m so there
is no functional change at this point. It just proves that using these
previously unused bits in the encoding of the flag word doesn't break anything.
The next patch will make each target preserve the current mapping of
everything to Constraint_m for itself while changing the target independent
implementation of the hook to return Constraint_Unknown appropriately. Each
target will then be adapted in separate patches to use appropriate Constraint_*
values.

Fix ProcessIO test failures
Summary:
There was a race condition regarding the output of the inferior process. The reading of the
output is performed on a separate thread, and there was no guarantee that the output will get
eventually consumed. Because of that, it was happening that calling Process::GetSTDOUT was not
returning anything even though the process was terminated and would definitely not produce any
further output. This was usually happening only under very heavy system load, but it can be
reproduced by placing an usleep in the stdio thread (Process::STDIOReadThreadBytesReceived).
This patch addresses this by adding synchronization capabilities to the Communication thread.
After calling Communication::SynchronizeWithReadThread one can be sure that all pending input has
been processed by the read thread. This function is then called after every public event which
stops the process to obtain the entire process output.
Test Plan: TestProcessIO.py should now succeed every time instead of flaking in and out.

Driver: Keep -isysroot flags in crash scripts if we're dumping a VFS
For crashes with a VFS (ie, with modules), the -isysroot flag is often
necessary to reproduce the crash. This is especially true if some
modules need to be rebuilt, since without the sysroot they'll try to
read headers that are outside of the VFS.
I find it likely that we should keep some of the other -i flags in

it seems better to be conservative.

Move the DataLayout to the generic TargetMachine, making it mandatory.
Summary:
I don't know why every singled backend had to redeclare its own DataLayout.
There was a virtual getDataLayout() on the common base TargetMachine, the
default implementation returned nullptr. It was not clear from this that
we could assume at call site that a DataLayout will be available with
each Target.
Now getDataLayout() is no longer virtual and return a pointer to the
DataLayout member of the common base TargetMachine. I plan to turn it into
a reference in a future patch.
The only backend that didn't have a DataLayout previsouly was the CPPBackend.
It now initializes the default DataLayout. This commit is NFC for all the
other backends.

[PowerPC] Remove canFoldAsLoad from instruction definitions
The PowerPC backend had a number of loads that were marked as canFoldAsLoad
(and I'm partially at fault here for copying around the relevant line of
TableGen definitions without really looking at what it meant). This is not
right; PPC (non-memory) instructions don't support direct memory operands, and
so there is nothing a 'foldable' instruction could be folded into.
Noticed by inspection, no test case.
The one thing we might lose by doing this is ability to fold some loads into
stackmap/patchpoint pseudo-instructions. However, this was untested, and would
not obviously have worked for extending loads, and I'd rather re-add support
for that once it can be tested.

Fix a comparison function to actually be a SWO so that it conforms to
the spec required by std::sort and friends.
Ordering things this way also dramatically simplifies the code as
short-circuit ensures we can skip all of the negative tests.
I've left one FIXME where we're establishing a fairly arbitrary
ordering. Previously, the function compared all types as equal except
for the ones it explicitly handled, but it didn't delegate correctly to
the atomflags when doing so, and so it would fail to be a SWO. The two
possible fixes are to stop comparing the atom flags entirely, or to
establish some arbitrary ordering of the types.
Since it was pure luck which ordering of unequal types we ended up with
previously (the caller was std::sort, not std::stable_sort) I chose to
make the ordering explicit and guaranteed. This seems like the best
conservative approach as I suspect we would want to switch to
stable_sort otherwise in order to have deterministic output.

the stack.
But byval handling had grown over many years, and had multiple layers of cruft
trying to compensate for each other and calculate padding correctly. This only
really needs to be done once, in the HandleByVal function. Elsewhere should
just do what it's told by that call.
