Nico Weber f9e37be2d6 Follow-up to r217302 and r227555: Don't crash on inline ~A::A() if A is an int.
Even with r227555, this still crashed:

  struct S {
    int A;
    ~A::A() {}
  };

That's because ParseOptionalCXXScopeSpecifier()'s call to
ActOnCXXNestedNameSpecifier() doesn't mark the scope spec as invalid if sema
thought it's a good idea to fixit-correct "::" to ":".  For the diagnostic
improvement done in r217302, we never want :: to be interpreted as :, so fix
this by setting ColonSacred to false temporarily.

Fraser Cormack cc6e894587 Fix OpenCL 1.2 double as an optional core feature behaviour
In OpenCL 1.2, using double no longer requires using the pragma cl_khr_fp64,
instead a kernel is allowed to use double, but must first have queried
clGetDeviceInfo's CL_DEVICE_DOUBLE_FP_CONFIG.

Page 197, section 6.1.1 of the OpenCL 1.2 specification has a footnote 23
describing this behaviour.

I've also added test cases such that the pragma must be used if targeting
OpenCL 1.0 or 1.1, but is ignored in 1.2 and 2.0.

Filipe Cabecinhas 28f353c7d0 Add some more PS4 driver settings related to rtti and exceptions.
Summary:
The PS4 defaults to -fno-rtti, and has to have rtti enabled when enabling
exceptions.

This commit makes clang add the -fno-rtti by default on the PS4, unless
-frtti was passed in.

It also diagnoses misuses for the PS4:
- Exceptions need rtti. Warn and enable rtti if no rtti flag was passed,
  error if -fno-rtti was passed.

I also added a more general warning for when -fno-rtti is the default
(currently it's only on the PS4) and the vptr sanitizer is on.

Fixed a few tests, due to different flag order when passing cc1 arguments.

David Majnemer 310e3a8f60 MS ABI: Implement proper support for setjmp
On targets which use the MSVCRT, setjmp is a macro which expands to
_setjmp or _setjmpex.

_setjmp and _setjmpex have a secret, hidden argument which is not listed
in the function prototype on X64 and WoA.  This hidden argument always
seems to be the frame pointer.

_setjmpex isn't used on X86, _setjmp is magically replaced with a call
to _setjmp3.  The second argument is zero for 'normal' setjmp/longjmp
pairs, otherwise it is a count of additional variadic arguments.  This
is used when setjmp appears inside of a try or __try.

It is not safe to use a pointer to setjmp because _setjmp, _setjmpex and
_setmp3 are not compatible with setjmp.

Also guard against said infinite recursion by adding an assert that will
trigger if CorrectDelayedTyposInExpr is called before a previous call to
CorrectDelayedTyposInExpr returns (i.e. if the TreeTransform run by
CorrectDelayedTyposInExpr calls a sequence of methods that
end up calling CorrectDelayedTyposInExpr, as the new test case had done
prior to this commit). Fixes PR22292.

David Blaikie 298720d324 DebugInfo: Attribute implicit boolean tests to the expression being tested, not to the outer use of that expression.
This is half a fix for a GDB test suite failure that expects to start at
'a' in the following code:

  void func(int a)
    if (a
        &&
	b)
	...

But instead, without this change, the comparison was assigned to '&&'
(well, worse actually - because there was a chained 'a && b && c' and it
was assigned to the second '&&' because of a recursive application of
this bug) and then the load folded into the comparison so breaking on
the function started at '&&' instead of 'a'.

The other part of this needs to be fixed in LLVM where it's ignoring the
location of the icmp and instead using the location of the branch
instruction.

The fix to the conditional operator is actually a no-op currently,
because the conditional operator's location coincides with 'a' (the
start of the conditional expression) but should probably be '?' instead.
See the FIXME in the test case that mentions the ARCMigration tool
failures when I tried to make that change.

Francisco Lopes da Silva 0c010cddb3 Improves overload completion result chunks.
The code building the code completion string for overloads was providing
less detail compared to the one building completion strings for function
declarations. There was no information about optionals and no information
about what's a parameter and what's a function identifier, everything
besides ResultType, CurrentParameter and special characters was classified
as Text.

This makes code completion strings for overload candidates to follow a
pattern very similar, but not identical, to the one in use for function
declarations:

 - return type chunk: ResultType
 - function identifier chunk: Text
 - parameter chunks: Placeholder
 - optional parameter chunks: Optional
 - current parameter chunk: CurrentParameter
