When using Visual Studio 2015, cmake now puts the native visualizers in llvm.sln, so the developer automatically sees custom visualizations.
Much thanks to ariccio who provided extensive help on this change. (manual installation still needed on VS2013)

This is an enhancement of the existing update_llc_test_checks.py script.
It adds some of the functionality from the script used in D17999 to make
the IR checking more flexible.
The bad news:
This actually is 'My First Python Program'. Thus, it's likely that I have
violated all best practices of Python programming if I've made a functional
change from the original program. If you see anything that's obviously
wrong, please let me know or feel free to fix it. I didn't even read any
documentation...
The good news:
I tested this on ~10 existing opt/llc regression tests, and it does what
I hoped for. It produces exact checking for IR regression tests and doesn't
signficantly change the existing llc-with-x86-target asm checking. The opt
tests that were modified in r263667, r263668, r263674, and r263679 are
examples of the expected results, except that this version of the script
puts the check lines ahead of the IR to follow the existing llc/asm
behavior.
If there are no complaints/fallout, we should be able to remove the
original script. Extending this script to be used for non-x86 and clang
regression tests would be the expected follow-up steps.

We lose the 'utils' directory name in our advertising line with
this change. We could retain that, but I don't see the point.
This removes a dependency for making the script apply to more than
'llc'. Ie, we'll want to change the script name if it works with
opt/clang too.
llvm-svn: 264310
The goal is to enhance this script to be used with opt and clang:
Break 'main' into functions and change variable names to be more
generic because we want to handle more than x86 asm output.
llvm-svn: 264307
The goal is to enhance this script to be used with opt and clang:
Group all of the regexes together, so it's easier to see what's going on.
This will make it easier to break main() up into pieces too.
Also, note that some of the regexes are for x86-specific asm.

In the <DisplayString> of PointerIntPair , I cast the pointer to the actual type, so VS can leverage it while visualizing, not unlike the recent change to PointerUnion visualization.
In the expansion, the current code is casting to the incorrect type (wrong number of stars), so I fixed that as well.

Summary:
The multiprocessing.Queue.put() call can hang if we try queueing all the
tests before starting to take them out of the queue.
The current implementation hangs if tests exceed 2^^15, on Mac OS X.
This might happen with a ninja check-all if one has a bunch of llvm
projects.

This lets us for example start running the unit test suite early. For
'check-llvm' on my machine, this drops the tim e from 44s to 32s!!!!!
It's pretty ugly. I barely know how to write Python, so feel free to
just tell me how I should write it instead. =D Thanks to Filipe and
others for help.

TableGen checks at compiletime that for scheduling models with
"CompleteModel = 1" one of the following holds:
- Is marked with the hasNoSchedulingInfo flag
- The instruction is a subclass of Sched
- There are InstRW definitions in the scheduling model
Typical steps necessary to complete a model:
- Ensure all pseudo instructions that are expanded before machine
scheduling (usually everything handled with EmitYYY() functions in
XXXTargetLowering).
- If a CPU does not support some instructions mark the corresponding
resource unsupported: "WriteRes<WriteXXX, []> { let Unsupported = 1; }".
- Add missing scheduling information.

This introduces a new flag that indicates that a specific instruction
will never be present when the MachineScheduler runs and therefore needs
no scheduling information.
This is in preparation for an upcoming commit which checks completeness
of a scheduling model when tablegen runs.

Previosy, if actual instruction have one of optional operands then other optional operands listed before this also should be presented.
For example instruction v_fract_f32 v0, v1, mul:2 have one optional operand - OMod and do not have optional operand clamp. Previously this was not allowed because clamp is listed before omod in AsmString:
string AsmString = "v_fract_f32$vdst, $src0_modifiers$clamp$omod";
Making this work required some hacks (both OMod and Clamp match classes have same PredicateMethod).
Now, if MatchInstructionImpl meets formal optional operand that is not presented in actual instruction it skips this formal operand and tries to match current actual operand with next formal.

[AMDGPU] Assembler: Check immediate types for several optional operands in predicate methods
With this change you should place optional operands in order specified by asm string:
clamp -> omod
offset -> glc -> slc -> tfe
Fixes for several tests.

Combinations of suffixes that look useful are actually ignored;
complaining about them will avoid mistakes.

Currently you can't specify node properties like commutativity on
a PatFrag. If you want to create a PatFrag on a commutative node
with a hasOneUse predicate, this enables you to specify that the
PatFrag is also commutable.

Summary:
This patch adds Windows support for a few of the llvm-config commands,
including cflags, ldflags, libs, and system-libs.
Currently llvm-config is untested, so this patch adds tests for the
commands that it fixes as well.

Summary:
This makes it possible to specify some operands as optional to the AsmMatcher.
Setting this field to true will prevent the AsmMatcher from emitting
'too few operands' errors when there are missing optional operands.
