39247cb1d1 [CMake] Support multi-target runtimes build
This changes adds support for building runtimes for multiple
different targets using LLVM runtimes directory.

The implementation follow the model used already by the builtins
build which already supports this option. To specify the runtimes
targets to be built, use the LLVM_RUNTIME_TARGETS variable, where
the valuae is the list of targets to build runtimes for. To pass
a per target variable to the runtimes build, you can set
RUNTIMES_<target>_<variable> where <variable> will be passed to the
runtimes build for <target>.

Each runtime target (except for the default one) will be installed
into lib/<target> subdirectory. Build targets will be suffixed with
the target name.

3f91c64c16 [Dominators] Use a custom DFS implementation
Summary:
Custom DFS implementation allows us to skip over certain nodes without adding them to the visited map, which is not easily doable with llvm's dfs iterators. What's more, caching predecessors becomes easy.

This patch implements a single DFS function (template) for both forward and reverse DFS, which should be easier to maintain then separate two ones.

Skipping over nodes based on a predicate will be necessary later to implement incremental updates.

There also seems to be a very slight performance improved when bootstrapping clang with this patch on my machine (3:28s -> 3:26s) .

8f85685860 Enhance synchscope representation
OpenCL 2.0 introduces the notion of memory scopes in atomic operations to
  global and local memory. These scopes restrict how synchronization is
  achieved, which can result in improved performance.

  This change extends existing notion of synchronization scopes in LLVM to
  support arbitrary scopes expressed as target-specific strings, in addition to
  the already defined scopes (single thread, system).

  The LLVM IR and MIR syntax for expressing synchronization scopes has changed
  to use *syncscope("<scope>")*, where <scope> can be "singlethread" (this
  replaces *singlethread* keyword), or a target-specific name. As before, if
  the scope is not specified, it defaults to CrossThread/System scope.

  Implementation details:
    - Mapping from synchronization scope name/string to synchronization scope id
      is stored in LLVM context;
    - CrossThread/System and SingleThread scopes are pre-defined to efficiently
      check for known scopes without comparing strings;
    - Synchronization scope names are stored in SYNC_SCOPE_NAMES_BLOCK in
      the bitcode.

847573ba4e [ARM, ELF] Don't shift movt relocation offsets
For ELF, a movw+movt pair is handled as two separate relocations.
If an offset should be applied to the symbol address, this offset is
stored as an immediate in the instruction (as opposed to stored as an
offset in the relocation itself).

Even though the actual value stored in the movt immediate after linking
is the top half of the value, we need to store the unshifted offset
prior to linking. When the relocation is made during linking, the offset
gets added to the target symbol value, and the upper half of the value
is stored in the instruction.

This makes sure that movw+movt with offset symbols get properly
handled, in case the offset addition in the lower half should be
carried over to the upper half.

This makes the output from the additions to the test case match
the output from GNU binutils.

For COFF and MachO, the movw/movt relocations are handled as a pair,
and the overflow from the lower half gets carried over to the movt,
so they should keep the shifted offset just as before.

5cc2236f0f [Support] - Add bad alloc error handler for handling allocation malfunctions
Summary:
Patch by Klaus Kretzschmar

We would like to introduce a new type of llvm error handler for handling
bad alloc fault situations.  LLVM already provides a fatal error handler
for serious non-recoverable error situations which by default writes
some error information to stderr and calls exit(1) at the end (functions
are marked as 'noreturn').

For long running processes (e.g. a server application), exiting the
process is not an acceptable option, especially not when the system is
in a temporary resource bottleneck with a good chance to recover from
this fault situation. In such a situation you would rather throw an
exception to stop the current compilation and try to overcome the
resource bottleneck. The user should be aware of the problem of throwing
an exception in bad alloc situations, e.g. you must not do any
allocations in the unwind chain. This is especially true when adding
exceptions in existing unfamiliar code (as already stated in the comment
of the current fatal error handler)

So the new handler can also be used to distinguish from general fatal
error situations where recovering is no option.  It should be used in
cases where a clean unwind after the allocation is guaranteed.

This patch contains:
- A report_bad_alloc function which calls a user defined bad alloc
  error handler. If no user handler is registered the
  report_fatal_error function is called. This function is not marked as
  'noreturn'.
- A install/restore_bad_alloc_error_handler to install/restore the bad
  alloc handler.
- An example (in Mutex.cpp) where the report_bad_alloc function is
  called in case of a malloc returns a nullptr.

If this patch gets accepted we would create similar patches to fix
corresponding malloc/calloc usages in the llvm code.

Use CHECK-NEXT for the comparison sequence, to make sure we don't get
any unexpected instructions in the middle of our flag manipulation
efforts.

eb75f906da [PM] Another post-commit fix in NewPMDriver
There were two errors in the parsing of opt's command line options for
extension point pipelines. The EP callbacks are not supposed to return a
value. To check the pipeline text for correctness, I now try to parse it
into a temporary PM object, and print a message on failure. This solves
the compile time error for the lambda return type, as well as correctly
handles unparsable pipelines now.
