Add `llvm::uninitialized_copy` that accepts a range instead of start/end
iterator for the source of the copy.

These files satisfy all of the following:

- misc-include-cleaner indicates that these files do not need
  Endian.h.
- They do not mention "endian" anywhere.
- They do not include any *.inc or *.def, which could need
  llvm::support::endian.

Note that llvm::support::endianness has been renamed to
llvm::endianness while becoming an enum class as opposed to an enum.
This patch replaces llvm::support::{big,little,native} with
llvm::endianness::{big,little,native}.

This adds support for generating Chrome-tracing .json profile traces in
the LLD COFF driver.

Also add the necessary time scopes, so that the profile trace shows in
great detail which tasks are executed.

As an example, this is what we see when linking a Unreal Engine
executable:

We hit this in Chromium builds where the PDB file was just under 4GB,
but the stream directory was actually too large to be correctly
represented.

llvm-pdbutil would error about this in llvm::msf::validateSuperBlock,
but lld should not write such PDB files in the first place.

(Reapply after revert in e9ce1a588030d8d4004f5d7e443afe46245e9a92 due to
Fuchsia test failures. Removed changes in lib/ExecutionEngine/ other
than error categories, to be checked in more detail and reapplied
separately.)

Bulk remove many of the more trivial uses of ManagedStatic in the llvm
directory, either by defining a new getter function or, in many cases,
moving the static variable directly into the only function that uses it.

This reverts commit e6f1f062457c928c18a88c612f39d9e168f65a85.

Reverting due to a failure on the fuchsia-x86_64-linux buildbot.
