ae65e281f3 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.

8f4cf9cdb7 [MSF] Fix FPM interval calcluation
We have some code to try to determine how many pieces an MSF
Free Page Map is split into, and this code had an off by one
error which would cause the calculation to be incorrect when
there were exactly 4096*k + 1 blocks in an MSF file.

Original investigation and patch outline by Colden Cullen.

1e25f820c0 [pdb/lld] Write a valid FPM.
The PDB reserves certain blocks for the FPM that describe which
blocks in the file are allocated and which are free.  We weren't
filling that out at all, and in some cases we were even stomping
it with incorrect data.  This patch writes a correct FPM.

311adaa4ee [pdbutil] Add a command to dump the FPM.
Recently problems have been discovered in the way we write the FPM
(free page map).  In order to fix this, we first need to establish
a baseline about what a correct FPM looks like using an MSVC
generated PDB, so that we can then make our own generated PDBs
match.  And in order to do this, the dumper needs a mode where it
can dump an FPM so that we can write tests for it.

This patch adds a command to dump the FPM, as well as a test against
a known-good PDB.

2269779262 [msf] Resubmit "Rename Msf -> MSF".
Previously this change was submitted from a Windows machine, so
changes made to the case of filenames and directory names did
not survive the commit, and as a result the CMake source file
names and the on-disk file names did not match on case-sensitive
file systems.

I'm resubmitting this patch from a Linux system, which hopefully
allows the case changes to make it through unfettered.
