Added intrinsics for the instructions. CC parameter of the intrinsics was changed from i8 to i32 according to the spec.

Summary:
These are remnants of the thread state coordinator, which are now unnecessary. I have basically
inlined the callbacks. No functional change.
Test Plan: Tests continue to pass.

- Fix the formatting of the "Exceptions and SEH" section.
- Make the "Complete" text for "Thread-safe initialization of local
statics" green.
llvm-svn: 236706
Summary:
This changes add -target-attach and -target-detach.
-target-attach allows lldb-mi to attach to an existing process by it's process id, matching gdb mi's syntax of '-target-attach <pid'. Additionally, support has been added for attaching to a process by name using '-target-attach -n <name>'. Combining this with --waitfor will allow lldb mi to attach to a process by name when the process starts.
-target-detach simply detaches from the current process
Patch from chuckr@microsoft.com
Test Plan: I have added three tests, one each for -target-attach <pid>, -target-attach -n <name>, and -target-attach -n <name> --waitfor

Fix for codegen of static variables declared inside of captured statements. Captured statements are actually a transparent DeclContexts, so we have to skip them when trying to get a mangled name for statics.

The MSVC 2015 ABI utilizes a rather straightforward adaptation of the
algorithm found in the appendix of N2382. While we are here, implement
support for emitting cleanups if an exception is thrown while we are
intitializing a static local variable.

Summary:
One step further getting aggregate loads and store being optimized
properly. This will only handle struct with one element at this point.
Test Plan: Added unit tests for the new supported cases.

Summary:
- The address argument can now be an expression (e.g. &array), it's no longer restricted to being just a number literal.
- The -o (offset) option is now properly handled, not just silently ignored.
- The --thread option is now properly handled.
- A new --frame option has been added for consistency with GDB.
- Added a new test to verify old and new functionality.

Inner bodies of OpenMP worksharing loop-based constructs with dynamic or guided scheduling are allowed to be marked with !llvm.mem.parallel_loop_access metadata for better optimization. Worksharing constructs with static scheduling cannot be marked this way (according to OpenMP standard "A data dependence between the same logical iterations in two such loops is guaranteed").
Constructs with auto and runtime scheduling are also not marked because automatically chosen scheduling may be static also.

Fixed codegen for reduction operations min, max, && and ||. Codegen for them is quite similar and I was confused by this similarity.
Also added a call to kmpc_end_reduce() in atomic part of reduction codegen (call to kmpc_end_reduce_nowait() is not required).

If we have recognized that a conditional is constant at a particular location in the code (while trying to decide if we can simplify a conditional branch), we can eagerly replace that condition with a constant if it's definition is post dominated by the branch in question.
In practice, this ends up being a compile time savings at most. JumpThreading would have visited each using branch anyways. CVP would have visited the cmp itself again. Unless LVI gives up early, we shouldn't gain any addition power by doing this transformation early. What we do gain is simplicity and compile time.

If this works well we'll add more hooks (strcmp, etc).

Renames the original CreateGCStatepoint to CreateGCStatepointCall, and
moves invoke creating functionality from PlaceSafepoints.cpp to
IRBuilder.cpp.
This changes the labels generated for PlaceSafepoints/invokes.ll so use

This commit changes the 'skip' method in the 'KeyValueNode' class
to ensure that it doesn't dereference a null pointer when calling
the 'skip' method of its value child node. It also adds a unittest
that ensures that the crash doesn't occur.
This change is motivated by a patch that implements parsing
of YAML block scalars (http://reviews.llvm.org/D9503), as one
of the unittests in that patch triggered this problem.

This makes use of the new API which can remove attributes from a set given a builder.
This is much faster than creating a temporary set and reduces llc time by about 0.3% which was all spent creating temporary attributes sets on the context.
