Chandler Carruth 2946cd7010 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.

Zachary Turner d1de2f4f5e [llvm-pdbutil] Add support for dumping detailed module stats.
This adds support for dumping a summary of module symbols
and CodeView debug chunks.  This option prints a table for
each module of all of the symbols that occurred in the module
and the number of times it occurred and total byte size.  Then
at the end it prints the totals for the entire file.

Additionally, this patch adds the -jmc (just my code) option,
which suppresses modules which are from external libraries or
linker imports, so that you can focus only on the object files
and libraries that originate from your own source code.

Zachary Turner c3d8eec9e9 [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.

Zachary Turner 6c3e41bbd3 [llvm-pdbutil] Dump raw bytes of pdb name map.
This patch dumps the raw bytes of the pdb name map which contains
the mapping of stream name to stream index for the string table
and other reserved streams.

Zachary Turner 6b124f29e7 [llvm-pdbutil] Add the ability to dump raw bytes from the file.
Normally we can only make sense of the content of a PDB in terms
of streams and blocks, but in some cases it may be useful to dump
bytes at a specific absolute file offset.  For example, if you
know that some interesting data is at a particular location and
you want to see some surrounding data.

Zachary Turner 9940203a2c [llvm-pdbutil] Create a "bytes" subcommand.
This idea originally came about when I was doing some deep
investigation of why certain bytes in a PDB that we round-tripped
differed from their original bytes in the source PDB.  I found
myself having to hack up the code in many places to dump the
bytes of this substream, or that record.  It would be nice if
we could just do this for every possible stream, substream,
debug chunk type, etc.

It doesn't make sense to put this under dump because there's just
so many options that would detract from the more common use case
of just dumping deserialized records.  So making a new subcommand
seems like the most logical course of action.  In doing so, we
already have two command line options that are suitable for this
new subcommand, so start out by moving them there.
