Fangrui Song 6da3d8b19c [llvm] Replace LLVM_ATTRIBUTE_NORETURN with C++11 [[noreturn]]
[[noreturn]] can be used since Oct 2016 when the minimum compiler requirement was bumped to GCC 4.8/MSVC 2015.

Note: the definition of LLVM_ATTRIBUTE_NORETURN is kept for now.

Alexander Shaposhnikov 97702c3d92 [Object][MachO] Refine the interface of Slice
This patch performs a minor cleanup of the class Slice:
static methods and constructors which take a pointer but assume that
it's not null now take the argument by reference.

Sameer Arora df69492cdf [llvm-libtool-darwin] Refactor Slice and writeUniversalBinary
Refactoring `Slice` class and function `createUniversalBinary` from
`llvm-lipo` into  MachOUniversalWriter. This refactoring is necessary so
as to use the refactored code for creating universal binaries under
llvm-libtool-darwin.

Benjamin Kramer adcd026838 Make llvm::StringRef to std::string conversions explicit.
This is how it should've been and brings it more in line with
std::string_view. There should be no functional change here.

This is mostly mechanical from a custom clang-tidy check, with a lot of
manual fixups. It uncovers a lot of minor inefficiencies.

This doesn't actually modify StringRef yet, I'll do that in a follow-up.

Shoaib Meenai 16a9632558 Reapply [llvm-lipo] Implement -create (with hardcoded alignments)
This reapplies r366142 with a fix for the failing Windows test.

Original commit message:

Creates universal binary output file from input files. Currently uses
hard coded value for alignment.  Want to get the create functionality
approved before implementing the alignment function.
