Pete Cooper 1523925daa Fix crash from assert in r279466.
The assert in r279466 checks that we call the correct version of
Intrinsic::getName.  The version which accepts only an ID should not
be used for intrinsics with overloaded types.  The global-isel
code was calling the wrong version.  The test CodeGen/AArch64/GlobalISel/arm64-irtranslator.ll
will ensure that we call the correct version from now on.

Richard Smith 2fbcbb7b38 Fix regression introduced by r279164: only pass definitions as the PatternDef
to DiagnoseUninstantiableTemplate, teach hasVisibleDefinition to correctly
determine whether a function definition is visible, and mark both the function
and the template as visible when merging function template definitions to
provide hasVisibleDefinition with the relevant information.

The change to always pass the right declaration as the PatternDef to
DiagnoseUninstantiableTemplate also caused those checks to happen before other
diagnostics in InstantiateFunctionDefinition, giving worse diagnostics for the
same situations, so I sunk the relevant diagnostics into
DiagnoseUninstantiableTemplate. Those parts of this patch are based on changes
in reviews.llvm.org/D23492 by Vassil Vassilev.

Duncan P. N. Exon Smith 9f5c83b914 ADT: Separate some list manipulation API into ilist_base, NFC
Separate algorithms in iplist<T> that don't depend on T into ilist_base,
and unit test them.

While I was adding unit tests for these algorithms anyway, I also added
unit tests for ilist_node_base and ilist_sentinel<T>.

To make the algorithms and unit tests easier to write, I also did the
following minor changes as a drive-by:
- encapsulate Prev/Next in ilist_node_base to so that algorithms are
  easier to read, and
- update ilist_node_access API to take nodes by reference.

There should be no real functionality change here.

Tim Shen 608ca2504a [ADT] Actually mutate the iterator VisitStack.back().second, not its copy.
Summary: Before the change, *Opt never actually gets updated by the end
of toNext(), so for every next time the loop has to start over from
child_begin(). This bug doesn't affect the correctness, since Visited prevents
it from re-entering the same node again; but it's slow.

Bruno Cardoso Lopes 25f02cfc52 [SemaObjC] Do not RebuildObjCMessageExpr without valid method decl
Fix crash-on-invalid in ObjC Sema by avoiding to rebuild a message
expression to a 'super' class in case the method to call does not exist
(i.e. comes from another missing identifier).

In this case, the typo transform is invoked upon the message expression
in an attempt to solve a typo in a 'super' call parameters, but it
crashes since it assumes the method to call has a valid declaration.

Philip commented on r279113 to ask for better comments as to
when to use the different versions of getName.  Its also possible
to assert in the simple case that we aren't an overloaded intrinsic
as those have to use the more capable version of getName.

Matt Arsenault 78fc9daf8d AMDGPU: Split SILowerControlFlow into two pieces
Do most of the lowering in a pre-RA pass. Keep the skip jump
insertion late, plus a few other things that require more
work to move out.

One concern I have is now there may be COPY instructions
which do not have the necessary implicit exec uses
if they will be lowered to v_mov_b32.

Matt Arsenault 88d7da01ca AMDGPU: Handle structs directly in AMDGPUABIInfo
Structs are currently handled as pointer + byval, which makes AMDGPU
LLVM backend generate incorrect code when structs are used. This patch
changes struct argument to be handled directly and without flattening,
which Clover (Mesa 3D Gallium OpenCL state tracker) will be able to
handle. Flattening would expand the struct to individual elements and
pass each as a separate argument, which Clover can not
handle. Furthermore, such expansion does not fit the OpenCL
programming model which requires to explicitely specify each argument
index, size and memory location.

James Molloy 5bf2114265 [SimplifyCFG] Rewrite SinkThenElseCodeToEnd
[Recommitting now an unrelated assertion in SROA is sorted out]

The new version has several advantages:
  1) IMSHO it's more readable and neater
  2) It handles loads and stores properly
  3) It can handle any number of incoming blocks rather than just two. I'll be taking advantage of this in a followup patch.

With this change we can now finally sink load-modify-store idioms such as:

    if (a)
      return *b += 3;
    else
      return *b += 4;

    =>

    %z = load i32, i32* %y
    %.sink = select i1 %a, i32 5, i32 7
    %b = add i32 %z, %.sink
    store i32 %b, i32* %y
    ret i32 %b

When this works for switches it'll be even more powerful.

Round 4. This time we should handle all instructions correctly, and not replace any operands that need to be constant with variables.

This was really hard to determine safely, so the helper function should be put into the Instruction API. I'll do that as a followup.

Tim Shen a5cc25e50f [SSP] Do not set __guard_local to hidden for OpenBSD SSP
__guard_local is defined as long on OpenBSD. If the source file contains
a definition of __guard_local, it mismatches with the int8 pointer type
used in LLVM. In that case, Module::getOrInsertGlobal() returns a
cast operation instead of a GlobalVariable. Trying to set the
visibility on the cast operation leads to random segfaults (seen when
compiling the OpenBSD kernel, which also runs with stack protection).

In the kernel, the hidden attribute does not matter. For userspace code,
__guard_local is defined as hidden in the startup code. If a program
re-defines __guard_local, the definition from the startup code will
either win or the linker complains about multiple definitions
(depending on whether the re-defined __guard_local is placed in the
common segment or not).

It also matches what gcc on OpenBSD does.

Thanks Stefan Kempf <sisnkemp@gmail.com> for the patch!
