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.

Sven van Haastregt 00111144e4 Print newline after banner for ModulePass
Before this commit, `llc -print-after-all` would print something like:

  *** IR Dump After Pre-ISel Intrinsic Lowering ***; ModuleID = ...

Emit a newline such that ModuleID appears on a line by its own.

Duncan P. N. Exon Smith 9f22752c4b IR: Skip -print-*-all after -print-*
This changes `-print-*` from transformation passes to analysis passes so
that `-print-after-all` and `-print-before-all` don't trigger.  This
avoids some redundant output.

Vedant Kumar 595ba1d548 [Debugify] Add -debugify-each for testing each pass in a pipeline
This adds a -debugify-each mode to opt which, when enabled, wraps each
{Module,Function}Pass in a pipeline with logic to add, check, and strip
synthetic debug info for testing purposes.

This mode can be used to test complex pipelines for debug info bugs, or
to collect statistics about the number of debug values & locations lost
throughout various stages of a pipeline.

Fedor Sergeev 94dca7c7ea IR printing improvement for function passes - introducing -print-module-scope
Summary:
When debugging function passes it happens to be rather useful to dump
the whole module before the transformation and then use this dump
to analyze this single transformation by running it separately
on that particular module state.

Introducing
    -print-module-scope
debugging option that forces all the function-level IR dumps
to become whole-module dumps.

This option builds on top of normal dumping controls like
   -print-before/after
   -filter-print-funcs

The plan is to eventually extend this option to cover other local passes
(at least loop passes) but that should go as a separate change.

Sean Silva fd03ac6a0c Consistently use ModuleAnalysisManager
Besides a general consistently benefit, the extra layer of indirection
allows the mechanical part of https://reviews.llvm.org/D23256 that
requires touching every transformation and analysis to be factored out
cleanly.

Thanks to David for the suggestion.

Chandler Carruth 164a2aa6f4 [PM] Remove support for omitting the AnalysisManager argument to new
pass manager passes' `run` methods.

This removes a bunch of SFINAE goop from the pass manager and just
requires pass authors to accept `AnalysisManager<IRUnitT> &` as a dead
argument. This is a small price to pay for the simplicity of the system
as a whole, despite the noise that changing it causes at this stage.

This will also helpfull allow us to make the signature of the run
methods much more flexible for different kinds af passes to support
things like intelligently updating the pass's progression over IR units.

While this touches many, many, files, the changes are really boring.
Mostly made with the help of my trusty perl one liners.

Thanks to Sean and Hal for bouncing ideas for this with me in IRC.

Chandler Carruth d174ce4ad1 [PM] Switch the new pass manager to use a reference-based API for IR
units.

This was debated back and forth a bunch, but using references is now
clearly cleaner. Of all the code written using pointers thus far, in
only one place did it really make more sense to have a pointer. In most
cases, this just removes immediate dereferencing from the code. I think
it is much better to get errors on null IR units earlier, potentially
at compile time, than to delay it.

Most notably, the legacy pass manager uses references for its routines
and so as more and more code works with both, the use of pointers was
likely to become really annoying. I noticed this when I ported the
domtree analysis over and wrote the entire thing with references only to
have it fail to compile. =/ It seemed better to switch now than to
delay. We can, of course, revisit this is we learn that references are
really problematic in the API.

Chandler Carruth 52eef8876e [PM] Add module and function printing passes for the new pass manager.
This implements the legacy passes in terms of the new ones. It adds
basic testing using explicit runs of the passes. Next up will be wiring
the basic output mechanism of opt up when the new pass manager is
engaged unless bitcode writing is requested.

Chandler Carruth e0af664cd8 [PM] Simplify the IR printing passes significantly now that a narrower
API is exposed.

This removes the support for deleting the ostream, switches the member
and constructor order arround to be consistent with the creation
routines, and switches to using references.

Chandler Carruth 9d805139bd [PM] Simplify the interface exposed for IR printing passes.
Nothing was using the ability of the pass to delete the raw_ostream it
printed to, and nothing was trying to pass it a pointer to the
raw_ostream. Also, the function variant had a different order of
arguments from all of the others which was just really confusing. Now
the interface accepts a reference, doesn't offer to delete it, and uses
a consistent order. The implementation of the printing passes haven't
been updated with this simplification, this is just the API switch.
