0d59f31d12 Add assertion to detect invalid registers in the PowerPC MC instruction lowering.
We have observed that noreg was being generated due to a bug in FastIsel and was not being detected during emission. It happens that in the Asm emission there is an assertion that detects this in getRegisterName() from the tbl-generated file PPCGenAsmWriter.inc. However, when emitting an Obj file, invalid registers can be emitted given that no check are made in getBinaryCodeFromInstr() from PPCGenMCCodeEmitter.inc. In order to cover all cases this adds an assertion for reg operands in LowerPPCMachineInstrToMCInst.

bba3cb95cc MS ABI: Delay default constructor closure checking until the outermost class scope ends
Previously, we would error out on this code because the default argument
wasn't parsed until the end of Outer:

  struct __declspec(dllexport) Outer {
    struct __declspec(dllexport) Inner {
      Inner(void *p = 0);
    };
  };

Now we do the checking on the closing brace of Outer instead of Inner.

d2647eaae6 Clean up iostream creation in preparation for conditionalizing streams.
Interleave the code for narrow and wide character streams. This makes it
more obvious that the two pieces of code are identical. Furthermore, it
makes it easier to conditionally compile support for certain streams, as
less #ifdef blocks are needed.

ea10d2477a [libcxx] Add <experimental/tuple> header for LFTS.
Summary:
This patch adds the `<experimental/tuple>` header (almost) as specified in the latest draft of the library fundamentals TS.

The main changes in this patch are:

1. Added variable template `tuple_size_v`
2. Added function `apply(Func &&, Tuple &&)`.
3. Changed `__invoke` to be `_LIBCPP_CONSTEXPR_AFTER_CXX11`.

The `apply(...)` implementation uses `__invoke` to invoke the given function. `__invoke` already provides the required functionality. Using `__invoke` also allows `apply` to be used on pointers to member function/objects as an extension. In order to facilitate this `__invoke` has to be marked `constexpr`. 



Test Plan:
Each new feature was tested. 

The test cases for `tuple_size_v` are as follows:
1. tuple_size_v.pass.cpp
  - Check `tuple_size_v` on cv qualified tuples, pairs and arrays.
2. tuple_size_v.fail.cpp
  - Test on reference type.
3. tuple_size_v_2.fail.cpp
  - Test on non-tuple
4. tuple_size_v_3.fail.cpp
  - Test on pointer type.

The test cases for tuple.apply are as follows:

1. arg_type.pass.cpp
   - Ensure that ref/pointer/cv qualified types are properly passed.
2. constexpr_types.pass.cpp
   - Ensure constexpr evaluation of apply is possible for `tuple` and `pair`.
3. extended_types.pass.cpp
   - Test apply on function types permitted by extension.
4. large_arity.pass.cpp
   - Test that apply can evaluated on tuples and arrays with large sizes.
5. ref_qualifiers.pass.cpp
   - Test that apply respects ref qualified functions.
6. return_type.pass.cpp
   - Test that apply returns the proper type.
7. types.pass.cpp
   - Test apply on function types as required by LFTS.

30934c0926 [ARM] Fix offset calculation in ARMBaseRegisterInfo::needsFrameBaseReg
The input offset to needsFrameBaseReg is a negative value below the top of the
stack frame, but when converting to a positive offset from the bottom of the
stack frame this value was negated, causing the final offset to be too large
by twice the input offset's magnitude. Fix that by not negating the offset.

0633fd7fb4 Verifier: Set --verify-debug-info=true by default
r186634 started verifying debug info, and r194986 disabled it by default
because it was too expensive to run the checks on every function (since
most of the graph was reachable from each function).

r206300 moved the checks to module-level to make it cheaper, but there
was already quite a bit of testcase bitrot (and the verifier would only
print `<badref>`) so I guess no one had time to turn it back on.

This does just that.  Upgrade scripts this past autumn and winter
probably fixed some of the bitrot, and this weekend I fixed the verifier
output (r232275, r232417, r232418) and thusly the remaining failing
testcases (r232290, r232415).

This is part of PR22777.

618d580ec9 asan: optimization experiments
The experiments can be used to evaluate potential optimizations that remove
instrumentation (assess false negatives). Instead of completely removing
some instrumentation, you set Exp to a non-zero value (mask of optimization
experiments that want to remove instrumentation of this instruction).
If Exp is non-zero, this pass will emit special calls into runtime
(e.g. __asan_report_exp_load1 instead of __asan_report_load1). These calls
make runtime terminate the program in a special way (with a different
exit status). Then you run the new compiler on a buggy corpus, collect
the special terminations (ideally, you don't see them at all -- no false
negatives) and make the decision on the optimization.

The exact reaction to experiments in runtime is not implemented in this patch.
It will be defined and implemented in a subsequent patch.

57f00f2f9c [libcxx] Move tuple_size and tuple_element overloads for pair and array out of !defined(_LIBCPP_HAS_NO_VARIADICS) block.
Summary:
There is no reason to guard `tuple_size`, `tuple_element` and `get<I>(...)` for pair and array inside of `<__tuple>` so that they are only available when we have variadic templates.
This requires there be redundant declarations and definitions. It also makes it easy to get things wrong.

For example the following code should compile (and does in c++11).
```
#define _LIBCPP_HAS_NO_VARIADICS
#include <array>

int main()
{
  static_assert((std::tuple_size<std::array<int, 10> volatile>::value == 10), "");
}
```

This patch lifts the non-variadic parts of `tuple_size`, `tuple_types`, and `get<I>(...)` to the top of `<__tuple>` where they don't require variadic templates. This patch also removes `<__tuple_03>` because there is no longer a need for it.

f68156015d Fix R0 use in PowerPC VSX store for FastIsel.
The VSX stores are sometimes generated with a undefined index register, causing %noreg to be used and R0 to be emitted later on. The semantics of the VSX store (e.g. stdsdx) requires R0 to be used as base if we want zero to be used in the computation of the effective address instead of the content of R0. This patch checks if no index register was generated and forces R0 to be used as base address.
