Nico Weber 7123bca7fb Fix debug info for Objective-C properties from class extensions after r251874
After r251874, properties from class extensions no longer show up in
ObjCInterfaceDecl::properties().  Make debug info emission explicitly
look for properties in class extensions before looking at direct properties.

Also add a test that checks for this.  There are three interesting cases:

1. A property is only declared in a class extension, and the @implementation
   is in a different file.  This used to generated a DIObjcProperty before
   r251874 and does again with this fix.

2. A property is declared as readonly in the class itself and redeclared as
   readwrite in a class extension. clang before r251874 put the DIObjcProperty
   on the first declaration. clang after r251874 didn't emit any DIObjcProperty,
   and clang with this fix puts it on the readwrite redeclaration (which is
   what lookup finds).  This seems like a progression.

3. Like 2, but with an @implementation in the same file.  In this case,
   the property debug info gets generated a second time through the ivar
   from the definition.  In this case, lookup and declaration code need
   to agree on the line number so that the DIObjcProperty isn't emitted
   twice.  In this case, clang before r251874 emitted one DIObjcProperty
   on the first declaration, clang with r251874 emitted one on the second
   declaration, and clang with this patch still does the latter.

Devin Coughlin ebeed88078 [analyzer] Support inlining lambda-converted blocks.
clang converts C++ lambdas to blocks with an implicit user-defined conversion
operator method on the lambda record. This method returns a block that captures a copy
of the lambda. To inline a lambda-converted block, the analyzer now calls the lambda
records's call operator method on the lambda captured by the block.

Stephen Hines 8267e7d456 LLDB JIT needs android vector passing rules.
Summary:
Looking into some recent issues with LLDBs expression parser highlighted that upstream clang passes vectors types differently to Android Open Source Project's clang for Arm Android targets.
This patch reflects the changes present in the AOSP and allows LLDB's JIT expression evaluation to work correctly for Arm Android targets when passing vectors.

Devin Coughlin dfde655461 [analyzer] Suppress stack address escape on CK_CopyAndAutoreleaseBlockObject.
Don't warn about addresses of stack-allocated blocks escaping if the block
region was cast with CK_CopyAndAutoreleaseBlockObject. These casts, which
are introduced in the implicit conversion operator for lambda-to-block
conversions, cause the block to be copied to the heap -- so the warning is
spurious.

This CL is for discussion how to better fix bit-filed layout compatibility issue with GCC (see PR25575 for test case and more details). Current clang behavior is compatible with GCC 4.1-4.3 series but it was fixed in 4.4+. Ignoring packed attribute looks very odd and because it was also fixed in GCC 4.4+, it makes sense also fix it in clang.

Richard Smith 0c6124ba82 PR17381: Treat undefined behavior during expression evaluation as an unmodeled
side-effect, so that we don't allow speculative evaluation of such expressions
during code generation.

This caused a diagnostic quality regression, so fix constant expression
diagnostics to prefer either the first "can't be constant folded" diagnostic or
the first "not a constant expression" diagnostic depending on the kind of
evaluation we're doing. This was always the intent, but didn't quite work
correctly before.

This results in certain initializers that used to be constant initializers to
no longer be; in particular, things like:

  float f = 1e100;

are no longer accepted in C. This seems appropriate, as such constructs would
lead to code being executed if sanitizers are enabled.

Samuel Antao 4af1b7b693 [OpenMP] Update target directive codegen to use 4.5 implicit data mappings.
Summary:
This patch implements the 4.5 specification for the implicit data maps. OpenMP 4.5 specification changes the default way data is captured into a target region. All the non-aggregate kinds are passed by value by default. This required activating the capturing by value during SEMA for the target region. All the non-aggregate values that can be encoded in the size of a pointer are properly casted and forwarded to the runtime library. On top of fixing the previous weird behavior for mapping pointers in nested data regions (an explicit map was always required), this also improves performance as the number of allocations/transactions to the device per non-aggregate map are reduced from two to only one - instead of passing a reference and the value, only the value passed.

Explicit maps will be added later on once firstprivate, private, and map clauses' SEMA and parsing are available.
