Also let clang-format-diff.py detect errors based on clang-format's
return code. Otherwise messages like "Can't find usable .clang-format,
falling back to LLVM style" can make it fail, which might be undesired.

This patch fixes an old FIXME by creating a MCTargetStreamer interface
and moving the target specific functions for ARM, Mips and PPC to it.

The ARM streamer is still declared in a common place because it is
used from lib/CodeGen/ARMException.cpp, but the Mips and PPC are
completely hidden in the corresponding Target directories.

I will send an email to llvmdev with instructions on how to use this.

The bool conversion operator on InstantiatingTemplate never added value and
only served to obfuscate the template instantiation routines.

This replaces the conversion and its callers with an explicit isInvalid()
function to make it clear what's going on at a glance.

No new testcases. However, this patch makes all supported JIT testcases in 
test/ExecutionEngine  pass on Sparc.

Remove unneeded MMX instruction definition by moving pattern to an equivalent instruction definition and removing the filtering from the disassembler table building.

Remove some instructions that existed to provide aliases to the assembler. Can be done with InstAlias instead. Unfortunately, this was causing printer to use 'vmovq' or 'vmovd' based on what was parsed. To cleanup the inconsistencies convert all 'vmovd' with 64-bit registers to 'vmovq', but provide an alias so that 'vmovd' will still parse.

Specifically make ConstructorInitializerAllOnOneLineOrOnePerLine work
nicely with BreakConstructorInitializersBeforeComma.

As described by Richard in https://groups.google.com/a/isocpp.org/d/msg/std-discussion/S1kmj0wF5-g/fb6agEYoL2IJ

we should allow:

template<typename S>
struct A {

template<typename T> static auto default_lambda() {
  return [](const T&) { return 42; };
}

template<class U = decltype(default_lambda<S>())>
  U func(U u = default_lambda<S>()) { return u; }

};

int run2 = A<double>{}.func()(3.14);

int run3 = A<char>{}.func()('a');

This patch allows the code using the same trickery that was used to allow the code in non-member functions at namespace scope.

Summary:
Operator new, new[], delete, and delete[] are all implicitly static when
declared inside a record.  CXXMethodDecl already knows this, but we need
to account for that before we pick the calling convention for the
function type.

The original code with enum "_" is intended to emulate scoped enums.
Now we have real scoped enums, so use it.

This is the first step in how I plan to get mach-o object files support into 
lld. We need to be able to test the mach-o Reader and Write on systems without 
a mach-o tools. Therefore, we want to support a textual way (YAML) to represent 
mach-o files.

MachONormalizedFile.h defines an in-memory abstraction of the content of mach-o  
files. The in-memory data structures are always native endianess and always
use 64-bit sizes. That internal data structure can then be converted to or
from three different formats: 1) yaml (text) encoded mach-o, 2) binary mach-o
files, 3) lld Atoms.

This patch defines the internal model and uses YAML I/O to implement the 
conversion to and from the model to yaml. The next patch will implement
the conversion from normalized to binary mach-o.

This patch includes unit tests to validate the yaml conversion APIs.

In r186373, we started merging attributes on typedefs, but this causes
us to try to merge attributes even if the previous declaration was not
a typedef.

Only merge the attributes if the previous decl was also a typedef.

An updated version of r191586 with bug fix.

Struct-path aware TBAA generates tags to specify the access path,
while scalar TBAA only generates tags to scalar types.

We should not generate a TBAA tag with null being the first field. When
a TBAA type node is null, the tag should be null too. Make sure we
don't decorate an instruction with a null TBAA tag.

Added a testing case for the bug reported by Richard with -relaxed-aliasing
and -fsanitizer=thread.
