David Majnemer 699dd04a13 [CodeGen] Don't crash classifying a union of an AVX vector and an int
We forgot to run postMerge after decided that the union had to be
classified as MEMORY.  This left us with Lo == MEMORY and Hi == SSEUp
which is an invalid combination.

This fixes PR24021.

Adrian Prantl 437105a4de llvm-objdump: Replace the -macho -raw option with a generic -raw-clang-ast
option that works with all object container formats.
Now that clang modules/PCH are object containers this option is useful to
to construct pipes like

  llvm-objdump -raw-clang-ast foo.pcm | llvm-bcanalyzer -

to inspect the AST contents in a PCH container.
Will be tested via clang.

Belatedly addresses review feedback for r233390.

Sean Callanan 007135e612 Fixed the C modules test case on Darwin by streamlining its code.
We don't need to do the fancy dance with checking whether the iterator
represents a #define -- in fact, that's the wrong thing to do.  The thing to do
is check whether the highest-priority module that did something to the module
#defined or #undefd it.  If it #defined it, then the MacroInfo* will be non-NULL
and we're good to go.

Reid Kleckner e69bdb8619 [WinEH] Make llvm.x86.seh.restoreframe work for stack realignment prologues
The incoming EBP value points to the end of a local stack allocation, so
we can use that to restore ESI, the base pointer. Once we do that, we
can use local stack allocations. If we know we need stack realignment,
spill the original frame pointer in the prologue and reload it after
restoring ESI.

Alex Lorenz 900b5cb2ab MIR Printer: Use a module slot tracker to print global address operands. NFC.
This commit adopts the 'ModuleSlotTracker' class, which was surfaced in r240842,
to print the global address operands. This change ensures that the slot tracker
won't have to be recreated every time a global address operand is printed,
making the MIR printing more efficient.

Reid Kleckner 60381791b5 Rename llvm.frameescape and llvm.framerecover to localescape and localrecover
Summary:
Initially, these intrinsics seemed like part of a family of "frame"
related intrinsics, but now I think that's more confusing than helpful.
Initially, the LangRef specified that this would create a new kind of
allocation that would be allocated at a fixed offset from the frame
pointer (EBP/RBP). We ended up dropping that design, and leaving the
stack frame layout alone.

These intrinsics are really about sharing local stack allocations, not
frame pointers. I intend to go further and add an `llvm.localaddress()`
intrinsic that returns whatever register (EBP, ESI, ESP, RBX) is being
used to address locals, which should not be confused with the frame
pointer.

Naming suggestions at this point are welcome, I'm happy to re-run sed.

Chris Bieneman 3765588f65 [CMake] Cleanup tools/CMakeLists.txt to take advantage of the auto-registration that was already partially working.
Summary:
The tools CMakeLists file already had implicit tool registration, but there were a few things off about it that needed to be altered to make it work. This change addresses all that. The changes in this patch are:

* factored out canonicalizing tool names from paths to CMake variables
* removed the LLVM_IMPLICIT_PROJECT_IGNORE mechanism in favor of LLVM_EXTERNAL_${nameUPPER}_BUILD which I renamed to LLVM_TOOL_${nameUPPER}_BUILD because it applies to internal and external tools
* removed ignore_llvm_tool_subdirectory() in favor of just setting LLVM_TOOL_${nameUPPER}_BUILD to Off
* Added create_llvm_tool_options() to resolve a bug in add_llvm_external_project() - the old LLVM_EXTERNAL_${nameUPPER}_BUILD would not work on a clean CMake directory because the option could be created after it was set in code.
* Removed all but the minimum required calls to add_llvm_external_project from tools/CMakeLists.txt

This patch adds ObjectFilePCHContainerOperations uses the LLVM backend
to put the contents of a PCH into a __clangast section inside a COFF, ELF,
or Mach-O object file container.

This is done to facilitate module debugging by makeing it possible to
store the debug info for the types defined by a module alongside the AST.
