lld: use `std::make_unique` (NFC)

The LLVM code base already uses C++14, use std::make_unique
to avoid the explicit constructor invocation via new and to avoid
spelling out the type twice.

Replace separator in OpenMP variant name mangling.

Nvidia PTX does not allow `.` to appear in identifiers, so OpenMP variant mangling now uses `$` to separate segments of the mangled name for variants of functions declared via `declare variant`.

[Darwin] Improve runtime OS version checks

Use a struct to represent numerical versions instead of encoding release
names in an enumeration. This avoids the need to extend the enumeration
every time there is a new release.

Rename `GetMacosVersion() -> GetMacosAlignedVersion()` to better reflect
how this is used on non-MacOS platforms.

RegAllocFast: Record internal state based on register units

Record internal state based on register units. This is often more
efficient as there are typically fewer register units to update
compared to iterating over all the aliases of a register.

[clang-tidy]: Added modernize-replace-disallow-copy-and-assign-macro

This check finds macro expansions of `DISALLOW_COPY_AND_ASSIGN(Type)` and
replaces them with a deleted copy constructor and a deleted assignment operator.

Before the `delete` keyword was introduced in C++11 it was common practice to
declare a copy constructor and an assignment operator as a private members. This
effectively makes them unusable to the public API of a class.

With the advent of the `delete` keyword in C++11 we can abandon the
`private` access of the copy constructor and the assignment operator and
delete the methods entirely.

Migration example:

class Foo {
  +  Foo(const Foo &) = delete;
  +  const Foo &operator=(const Foo &) = delete;
