[profile] Fix file contention causing dropped counts on Windows under…

… -fprofile-generate

See PR43425:
https://bugs.llvm.org/show_bug.cgi?id=43425

When writing profile data on Windows we were opening profile file with
exclusive read/write access.

In case we are trying to write to the file from multiple processes
simultaneously, subsequent calls to CreateFileA would return
INVALID_HANDLE_VALUE.

To fix this, I changed to open without exclusive access and then take a
lock.

test-release.sh: Update to fetch source from GitHub

Summary:
This also changes the test-release.sh script to build using the monorepo
layout instead of copying sub-projects into llvm/tools or llvm/projects.

Tag the 10.0.0 version bump.

The tag name, llvmorg-10-init, signifies that this is the initial commit
with major version number 10.

With this tag in place, git-describe can be used to generate nicer
names for commits on master, for example:

  $ git describe <hash>
  llvmorg-10-init-<number>-g<hash>

where <number> is the number of commits since this tag.

The plan is to add this kind of tag together with future version bumps.
