Nico Weber 13f7ddff17 Slightly simplify MappedBlockStream::createIndexedStream() calls
All callers had a PDBFile object at hand, so call
Pdb.createIndexedStream() instead, which pre-populates all the arguments
(and returns nullptr for kInvalidStreamIndex).

Also change safelyCreateIndexedStream() to only take the string index,
and update callers. Make the method public and call it in two places
that manually did the bounds checking before.

No intended behavior change.

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 6305545527 Resubmit "[llvm-pdbutil] rewrite the "raw" output style."
This resubmits commit c0c249e9f2ef83e1d1e5f166b50673d92f3579d7.

It was broken due to some weird template issues, which have
since been fixed.

Zachary Turner da504b794c Revert "[llvm-pdbutil] rewrite the "raw" output style."
This reverts commit 83ea17ebf2106859a51fbc2a86031b44d33696ad.

This is failing due to some strange template problems, so reverting
until it can be straightened out.

Zachary Turner b560fdf3b8 [llvm-pdbutil] rewrite the "raw" output style.
After some internal discussions, we agreed that the raw output style had
outlived its usefulness. It was originally created before we had even
thought of dumping to YAML, and it was intended to give us some insight
into the internals of a PDB file. Now we have YAML mode which does
almost exactly this but is more powerful in that it can round-trip back
to a PDB, which the raw mode could not do. So the raw mode had become
purely a maintenance burden.

One option was to just delete it. However, its original goal was to be
as readable as possible while staying close to the "metal" - i.e.
presenting the output in a way that maps directly to the underlying file
format. We don't actually need that last requirement anymore since it's
covered by the yaml mode, so we could repurpose "raw" mode to actually
just be as readable as possible.

This patch implements about 80% of the functionality previously in raw
mode, but in a completely different style that is more akin to what
cvdump outputs. Records are very compressed, often times appearing on
just one line. One nice thing about this is that it makes full record
matching easier, because you can grep for indices, names, and leaf types
on a single line often.

See the tests for some examples of what the new output looks like.

Note that this patch actually regresses the functionality of raw mode in
a few areas, but only because the patch was already unreasonably large
and going 100% would have been even worse. Specifically, this patch is
missing:

The ability to dump module debug subsections (checksums, lines, etc)
The ability to dump section headers
Aside from that everything is here. While goign through the tests fixing
them all up, I found many duplicate tests. They've been deleted. In
subsequent patches I will go through and re-add the missing
functionality.

Zachary Turner a8cfc29c9a Resubmit "[codeview] Make obj2yaml/yaml2obj support .debug$S..."
This was originally reverted because of some non-deterministic
failures on certain buildbots.  Luckily ASAN eventually caught
this as a stack-use-after-scope, so the fix is included in
this patch.

Zachary Turner 0085dce221 Revert "[codeview] Make obj2yaml/yaml2obj support .debug$S..."
This is causing failures on linux bots with an invalid stream
read.  It doesn't repro in any configuration on Windows, so
reverting until I have a chance to investigate on Linux.

Zachary Turner a3da4467fa [codeview] Make obj2yaml/yaml2obj support .debug$S/T sections.
This allows us to use yaml2obj and obj2yaml to round-trip CodeView
symbol and type information without having to manually specify the bytes
of the section. This makes for much easier to maintain tests. See the
tests under lld/COFF in this patch for example. Before they just said
SectionData: <blob> whereas now we can use meaningful record
descriptions. Note that it still supports the SectionData yaml field,
which could be useful for initializing a section to invalid bytes for
testing, for example.

Zachary Turner 990d0c8158 [llvm-pdbdump] Don't fail on PDBs with no ID stream.
Older PDBs don't have this.  Its presence is detected by using
the various "feature" flags that come at the end of the PDB
Stream.  Detect this, and don't try to dump the ID stream if the
features tells us it's not present.

Zachary Turner bd336e44d8 Rename llvm-pdbdump -> llvm-pdbutil.
This is to reflect the evolving nature of the tool as being
useful for more than just dumping PDBs, as it can do many other
things.
