Teresa Johnson 6107a4195d [ThinLTO] Remove functions resolved to available_externally from comdats
Summary:
thinLTOResolveWeakForLinkerModule needs to drop any preempted weak symbols
that were converted to available_externally from comdats, otherwise we
will get a verification failure (since available_externally is a
declaration for the linker, and no declarations can be in a comdat).

Justin Lebar 60dcc1344a Add the notion of deferred diagnostics.
Summary:
This patch lets you create diagnostics that are emitted if and only if a
particular FunctionDecl is codegen'ed.

This is necessary for CUDA, where some constructs -- e.g. calls from
host+device functions to host functions when compiling for device -- are
allowed to appear in semantically-correct programs, but only if they're
never codegen'ed.

Justin Lebar 9421ba6c02 [CUDA] Include CUDA headers before anything else.
Summary:
There's no point to --cuda-path if we then go and include /usr/include
first.  And if you install the right packages, Ubuntu will install (very
old) CUDA headers there.

Summary:
Replacement for part of D23518
This is the first patch to start reifying information about errors. It deals only with reifying shadow address-related information.
It will allow us to generate structures with all the relevant information for a given error so a debugger can get to them or they can be included in a core dump.

Wolfgang Pieb dfad9b20c9 Local variables whose address is taken and passed on to a call are described
in debug info using their stack slots instead of as an indirection of param reg + 0
offset. This is done by detecting FrameIndexSDNodes in SelectionDAG and generating
FrameIndexDbgValues for them. This ultimately generates DBG_VALUEs with stack
location operands.

Tobias Grosser 74814e1a07 Disable invariant load hoisting temporarily
With invariant load hoisting enabled the LLVM buildbots currently show some
miscompiles, which are possibly caused by invariant load hosting itself.
Confirming and fixing this requires a more in-depth analysis. To meanwhile get
back green buildbots that allow us to observe other regressions, we disable
invariant code hoisting temporarily. The relevant bug is tracked at:

Daniel Sanders 67f22ee24a [mips] XFAIL mips64el tests that fail on clang-cmake-mipsel
These tests were recently enabled and have never worked on this builder.

Three tests were sensitive to line number changes:
  test/msan/Linux/obstack.cc
  test/msan/chained_origin.cc
  test/msan/chained_origin_memcpy.cc
and this sensitivity will be addressed in a follow-up patch. Of these,
obstack.cc's sensitivity to line numbers is unexplained since it already uses
[[@LINE]].

Pavel Labath 1ac2b20d25 Fix expression evaluation with operator new
Summary:
referencing a user-defined operator new was triggering an assert in clang because we were
registering the function name as string "operator new", instead of using the special operator
enum, which clang has for this purpose. Method operators already had code to handle this, and now
I extend this to cover free standing operator functions as well. Test included.
