[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.

[profile] In Android, do not mkdir() dirs in GCOV_PREFIX

Summary:
In Android, attempting to mkdir() or even stat() top-level directories
like /data causes noisy selinux denials. During whole-system coverage
instrumentation, this causes a deluge of noisy messages that drown out
legitimate selinux denials, that should be audited and fixed.

To avoid this, skip creating any directory in GCOV_PREFIX (thereby
assuming that it exists).

- Android platform ensures that the GCOV_PREFIX used in Android is
created and read/writable by all processes.
- This only affects the Android platform (by checking against
__ANDROID_API_FUTURE__) and for apps built with Clang coverage, the
runtime will still create any non-existent parent directories for the
coverage files.

(Reland with changes) Adding a function for setting coverage output file.

Summary:
User code can open a file on its own and pass it to the runtime, rather than
specifying a name and having the runtime open the file. This supports the use
case where a process cannot open a file on its own but can receive a file
descriptor from another process.

Relanding https://reviews.llvm.org/D62541. The original revision unlocked
the file before calling flush, this revision fixes that.

Update the file headers across all of the LLVM projects in the monorepo
to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

[compiler-rt] Add a routine to specify the mode used when creating profile dirs.

Summary:
This patch introduces `llvm_profile_set_dir_mode` and `llvm_profile_get_dir_mode` to
the compiler-rt profile API.

Originally, profile data was placed into a directory that was created with a hard-coded
mode value of 0755 (for non-win32 builds). In certain cases, it can be helpful to create
directories with a different mode other than 0755. This patch introduces set/get
routines to allow users to specify a desired mode. The default remains at 0755.
