Kuba Brecka 4c80867ecf [sanitizer] On OS X, verify that interceptors work and abort if not, take 2
On OS X 10.11+, we have "automatic interceptors", so we don't need to use DYLD_INSERT_LIBRARIES when launching instrumented programs. However, non-instrumented programs that load TSan late (e.g. via dlopen) are currently broken, as TSan will still try to initialize, but the program will crash/hang at random places (because the interceptors don't work). This patch adds an explicit check that interceptors are working, and if not, it aborts and prints out an error message suggesting to explicitly use DYLD_INSERT_LIBRARIES.

TSan unit tests run with a statically linked runtime, where interceptors don't work. To avoid aborting the process in this case, the patch replaces `DisableReexec()` with a weak `ReexecDisabled()` function which is defined to return true in unit tests.

George Rimar 786e866fea [ELF] - -pie/--pic-executable option implemented
-pie
--pic-executable

Create a position independent executable.  This is currently only
 supported on ELF platforms.  Position independent executables are
 similar to shared libraries in that they are relocated by the
 dynamic linker to the virtual address the OS chooses for them
 (which can vary between invocations).  Like normal dynamically
 linked executables they can be executed and symbols defined in the
 executable cannot be overridden by shared libraries.

Bruno Cardoso Lopes b76c027717 Reapply [2]: [VFS] Add support for handling path traversals
This was applied twice r261551 and 263617 and later reverted because:

(1) Windows bot failing on unittests. Change the current behavior to do
not handle path traversals on windows.

(2) Windows bot failed to include llvm/Config/config.h in order to use
HAVE_REALPATH. Use LLVM_ON_UNIX instead, as done in lib/Basic/FileManager.cpp.

Handle ".", ".." and "./" with trailing slashes while collecting files
to be dumped into the vfs overlay directory.

Include the support for symlinks into components. Given the path:

/install-dir/bin/../lib/clang/3.8.0/include/altivec.h, if "bin"
component is a symlink, it's not safe to use `path::remove_dots` here,
and `realpath` is used to get the right answer. Since `realpath`
is expensive, we only do it at collecting time (which only happens
during the crash reproducer) and cache the base directory for fast lookups.

Overall, this makes the input to the VFS YAML file to be canonicalized
to never contain traversal components.

Sanjoy Das 312038872d [Statepoints] Separate out logic for statepoint directives; NFC
This splits out the logic that maps the `"statepoint-id"` attribute into
the actual statepoint ID, and the `"statepoint-num-patch-bytes"`
attribute into the number of patchable bytes the statpeoint is lowered
into.  The new home of this logic is in IR/Statepoint.cpp, and this
refactoring will support similar functionality when lowering calls with
deopt operand bundles in the future.

Pete Cooper c3b847db4f Require allocator parameter to YAML traits.
The allocator here can still be a nullptr, but this atleast makes the
single caller which needed nullptr be explicit about it.

Note, lld started always passing a parameter here as of r263680.  If
anything builds out of sync, that would be why errors may occur.

Pete Cooper 590872b0c2 Always pass an allocator to YAMLTraits.
The YAML traits new's when not passed an allocator to parse data.
For atom types, this is a leak as we don't destruct atoms.  For
the File here, we do actually destruct File's so that single case of
not using an allocator will be fine.

Should fix a bunch more leaks.

Pete Cooper 31275a1413 Use allocator in YAML code to avoid leaking atom content.
In lld we allocate atoms on an allocator and so don't run their
destructors.  This means we also shouldn't allocate memory inside
them without that also being on an allocator.

Sanjoy Das 70697ff74d Extract out a SelectionDAGBuilder::LowerAsStatepoint; NFC
Summary:
This is a step towards implementing "direct" lowering of calls and
invokes with deopt operand bundles into STATEPOINT nodes (as opposed to
having them mandatorily pass through RewriteStatepointsForGC, which is
the case today).

This change extracts out a `SelectionDAGBuilder::LowerAsStatepoint`
helper function that is able to lower a "statepoint like thing", and
uses it to lower `gc.statepoint` calls.  This is an NFC now, but in a
later change we will use `LowerAsStatepoint` to directly lower calls and
invokes with operand bundles without going through an intermediate
`gc.statepoint` IR representation.

FYI: I expect `SelectionDAGBuilder::StatepointInfo` will evolve as I add
support for lowering non gc.statepoints, right now it is fairly tightly
coupled with an IR level `gc.statepoint`.

- Rename getATOMIC to getSYNC, as llvm will soon be able to emit both
  '__sync' libcalls and '__atomic' libcalls, and this function is for
  the '__sync' ones.

- getInsertFencesForAtomic() has been replaced with
  shouldInsertFencesForAtomic(Instruction), so that the decision can be
  made per-instruction. This functionality will be used soon.

- emitLeadingFence/emitTrailingFence are no longer called if
  shouldInsertFencesForAtomic returns false, and thus don't need to
  check the condition themselves.
