Upgrade modf and frexp (#2266)
Fixes #2138

* Modf and frexp are upgraded to use the struct version of the
instruction and generate an explicit store whose flags can be upgraded
separately
* Fixed major bug where availability and visibility were reversed for
non-copy memory instructions
* Fixed bug where availability and visibility scope operands were reversed for copy memory
* Upgraded all opt tests to use SPV_ENV_UNIVERSAL_1_3
* Upgrade tests moved into unified tests and removed standalone test

Cleanup includes. (#1795)

Move the ir namespace to opt. (#1680)
This CL moves the files in opt/ to consistenly be under the opt::
namespace. This frees up the ir:: namespace so it can be used to make a
shared ir represenation.

61d8c0384b Add pass to reaplce invalid opcodes
Creates a pass that will remove instructions that are invalid for the
current shader stage.  For the instruction to be considered for replacement

1) The opcode must be valid for a shader modules.
2) The opcode must be invalid for the current shader stage.
3) All entry points to the module must be for the same shader stage.
4) The function containing the instruction must be reachable from an entry point.

Fixes #1247.

867451f49e Add scalar replacement
Adds a scalar replacement pass. The pass considers all function scope
variables of composite type. If there are accesses to individual
elements (and it is legal) the pass replaces the variable with a
variable for each composite element and updates all the uses.

Added the pass to -O
Added NumUses and NumUsers to DefUseManager
Added some helper methods for the inst to block mapping in context
Added some helper methods for specific constant types

No longer generate duplicate pointer types.

* Now searches for an existing pointer of the appropriate type instead
of failing validation
* Fixed spec constant extracts
* Addressed changes for review
* Changed RunSinglePassAndMatch to be able to run validation
 * current users do not enable it

Added handling of acceptable decorations.

* Decorations are also transfered where appropriate

Refactored extension checking into FeatureManager

* Context now owns a feature manager
 * consciously NOT an analysis
 * added some test
* fixed some minor issues related to decorates
* added some decorate related tests for scalar replacement

83228137e1 Re-format source tree - NFC.
Re-formatted the source tree with the command:

$ /usr/bin/clang-format -style=file -i \
    $(find include source tools test utils -name '*.cpp' -or -name '*.h')

This required a fix to source/val/decoration.h.  It was not including
spirv.h, which broke builds when the #include headers were re-ordered by
clang-format.

a771713e42 Adding an unique id to Instruction generated by IRContext
Each instruction is given an unique id that can be used for ordering
purposes. The ids are generated via the IRContext.

Major changes:
* Instructions now contain a uint32_t for unique id and a cached context
pointer
 * Most constructors have been modified to take a context as input
 * unfortunately I cannot remove the default and copy constructors, but
 developers should avoid these
* Added accessors to parents of basic block and function
* Removed the copy constructors for BasicBlock and Function and replaced
them with Clone functions
* Reworked BuildModule to return an IRContext owning the built module
 * Since all instructions require a context, the context now becomes the
basic unit for IR
* Added a constructor to context to create an owned module internally
* Replaced uses of Instruction's copy constructor with Clone whereever I
found them
* Reworked the linker functionality to perform clones into a different
context instead of moves
* Updated many tests to be consistent with the above changes
 * Still need to add new tests to cover added functionality
* Added comparison operators to Instruction
* Added an internal option to LinkerOptions to verify merged ids are
unique
* Added a test for the linker to verify merged ids are unique

* Updated MergeReturnPass to supply a context
* Updated DecorationManager to supply a context for cloned decorations

* Reworked several portions of the def use tests in anticipation of next
set of changes

76555bd4ba Tests: Add optional dependency on Effcee stateful matcher
Add Effcee as an optional dependency for use in tests.  In future it will
be a required dependency.

Effcee is a stateful pattern matcher that has much of the functionality
of LLVM's FileCheck, except in library form.  Effcee makes it much easier
to write tests for optimization passes.

Demonstrate its use in a test for the strength-reduction pass.

Update README.md with example commands of how to get sources.

Update Appveyor and Travis-CI build rules.

Also: Include test libraries if not SPIRV_SKIP_TESTS
- SPIRV_SKIP_TESTS is implied by SPIRV_SKIP_EXECUTABLES

f32d11f74b Add the IRContext (part 2): Add def-use manager
This change will move the instances of the def-use manager to the
IRContext.  This allows it to persists across optimization, and does
not have to be rebuilt multiple times.

Added test to ensure that the IRContext is validating and invalidating
the analyses correctly.

476cae6f7d Add the IRContext (part 1)
This is the first part of adding the IRContext.  This class is meant to
hold the extra data that is build on top of the module that it
owns.

The first part will simply create the IRContext class and get it passed
to the passes in place of the module.  For now it does not have any
functionality of its own, but it acts more as a wrapper for the module.

The functions that I added to the IRContext are those that either
traverse the headers or add to them.  I did this because we may decide
to have other ways of dealing with these sections (for example adding a
type pool, or use the decoration manager).

I also added the function that add to the header because the IRContext
needs to know when an instruction is added to update other data
structures appropriately.

Note that there is still lots of work that needs to be done.  There are
still many places that change the module, and do not inform the context.
That will be the next step.

1ca817a38e Use nullptr as the default message consumer to ignore all messages.
There is no difference between the previous IgnoreMessage() function
and a null std::function, from functionality's perspective.
The user can set nullptr as the MessageConsumer, so need to guard
against nullptr before calling the consumer anyway. It's better
we use it internally so that it may expose problems by us instead
of the user.

`SinglePassRunAndCheck()` and `SinglePassRunAndDisassemble()`. This is
