Vedant Kumar aa0cae6208 [ProfileData] Make a utility method public, NFC
The swift frontend needs to be able to look up PGO function name
variables based on the original raw function name. That's because it's
not possible to create PGO function name variables while emitting swift
IR. Instead, we have to create the name variables while lowering swift
IR to llvm IR, at which point we fix up all calls to the increment
intrinsic to point to the right name variable.

Jonathan Peyton 8a46c067ed [CMake] Fix Windows build problem for CMake versions < 3.3
Building libomp using CMake versions < 3.3 caused a link time error.  These
errors occurred because when assembling z_Windows_NT-586_asm.asm, the
definitions: OMPT_SUPPORT, _M_AMD64|_M_IA32 weren't defined on the command line.
To fix the problem, the COMPILE_FLAGS property for the assembly file is appended
to instead of the COMPILE_DEFINITIONS property being set.  For whatever reason, the
COMPILE_DEFINITIONS property doesn't pick up the definitions for assembly files
for the older CMake versions.

Geoff Berry 459b750871 [LSR] Create fewer redundant instructions.
Summary:
Fix LSRInstance::HoistInsertPosition() to check the original insert
position block first for a canonical insertion point that is dominated
by all inputs.  This leads to SCEV being able to reuse more instructions
since it currently tracks the instructions it creates for reuse by
keeping a table of <Value, insert point> pairs.

Created visualizer for PointerType, LValueReferenceType, RValueReferenceType, and TemplateParmType.
In addition, cleaned up the display of existing types to be more C++-like. For example, instead of

it now displays more readably as

Pavel Labath 78fc483980 [test] Persist packets between expect_gdbremote_sequence invocations
Summary:
Some tests (Hc_then_Csignal_signals_correct_thread, at least) were sending a "continue" packet in
one expect_gdbremote_sequence invocation, and "expecting" the stop-reply in another call. This
posed a problem, because the were packets were not persisted between the two invocations, and if
the stub was exceptionally fast to respond, the packet would be received in the first invocation
(where it would be ignored) and then the second invocation would fail because it could not find
the packet.

Since doing matching in two invocations seems like a reasonable use of the packet pump, instead
of fixing the test, I make sure the packet_pump supports this usage by making the list of
captured packets persistent.

Bruno Cardoso Lopes c9daaaedb6 Reapply: [VFS] Add support for handling path traversals
This is originally r261551, reverted because of windows bots failing on
unittests. Change the current behavior to do not handle path traversals
on windows.

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.

Eric Fiselier 7865b2e943 Add clang thread safety annotations to mutex and lock_guard. Patch by jamesr@google.com.
This adds clang thread safety annotations to std::mutex and
std::lock_guard so code using these types can use these types directly
instead of having to wrap the types to provide annotations. These checks
when enabled by -Wthread-safety provide simple but useful static

This patch introduces the Error classs for lightweight, structured,

described with user-defined types. Unlike exceptions however, errors are
represented as ordinary return types in the API (similar to the way
std::error_code is used).

For usage notes see the LLVM programmer's manual, and the Error.h header.
Usage examples can be found in unittests/Support/ErrorTest.cpp.
