a4342f3f44 Remove spvOpcodeIsObject().
Also
- Add type_id to spv_id_info_t.
- Use spv_id_info_t::type_id instead of words[1].
  Triggered some asserts on tests, where the code incorrectly assumed
  words[1] had a type.  Remove the asserts and handle gracefully.
- Add tests for OpStore of a label, a void, and a function.

3fade33c06 Qualify CMake function names with "spvtools" to avoid conflictions.
If a third-party project defines a CMake function with the same
name, by importing that project's CMake configuration, we may end
up overwriting our own copy. Qualify all defined functions to
reduce that probability.

276a724b25 Fix spvOpcodeIsScalarType() to include Boolean.
Remove redundant validations of OpConstant and OpConstantComposite.
Binary parser already performs these checks, so the validations can
never be triggered.

Enable bad-constant tests.

961f5dc544 Track uses and defs during parsing.
Replace two other, imperfect mechanisms for use-def tracking.

Use ValidationState_t::entry_points to track entry points.

Concentrate undefined-ID diagnostics in a single place.

Move validate_types.h content into validate.h due to increased
inter-dependency.

Track uses of all IDs: TYPE_ID, SCOPE_ID, ...

Also update some blurbs.

Fix entry-point accumulation and move it outside ProcessIds().

Remove validate_types.h from CMakeLists.txt.

Blurb for spvIsIdType.

Remove redundant diagnostics for undefined IDs.

Join "can not" and reformat.

383c83729e Since g++-4.9 has an ICE occasionally in travis add a retry.
Try to re-run the build with ninja -j 1 if the build fails,
this should reduce the number of build failures we see.

c741385976 Function and block layout checks. very basic CFG.
This adds function and block layout checks to the validator. Very
basic CFG code has been added to make sure labels and branches
are correctly ordered.

Also:
* MemoryModel and Variable instruction checks/tests
* Use spvCheckReturn instead of CHECK_RESULT
* Fix invalid SSA tests
* Created libspirv::spvResultToString in diagnostic.h
* Documented various functions and classes
* Fixed error messages
* Fixed using declaration for FunctionDecl enum class

7a35473573 Made compilation with gcc and clang more strict.
Added additional compilation flags to gcc and clang builds.
Adds -Wall -Wextra -Wno-long-long -Wshadow -Wundef -Wconversion
-WNo-sign-conversion and -Wno-missing-field-initializers
where appropriate.

Does not add -Wundef to tests, because GTEST tests undefined
macros all over the place.

43401d2ed0 Support 16-bit float in assembler and disassembler

16-bit floats are always disassembled into hex-float format,
but can be assembled from floating point or hex-float inputs.

a3d0d3c719 Initial logical layout validation
* Validates module level instructions for logical layout
  conformance
* Does not validate:
  1. Function logical layout
  2. Minor cases with OpVariable
  3. Missing MemoryModel instruction in module
  4. Order of function definition and function declaration
* 782 unit tests for logical layout

411de16386 Fix setting of off-by-default cmake options
An enclosing CMake project should be able to set the
off-by-default CMake options in SPIRV-Tools by just doing:
  set(SPIRV_SKIP_EXECUTABLES ON)
instead of
  set(SPIRV_SKIP_EXECUTABLES ON CACHE BOOL "" FORCE)

Also, fix the SPIRV_WARN_EVERYTHING so it understands which options
to send to Clang vs. GCC.

Note: With SPIRV_WARN_EVERYTHING enabled, the code doesn't
compil with either Clang or GCC.

f76e0f5231 Basic SSA Validation
Most uses of an ID must occur after the definition
of the ID.  Forward references are allowed for
things like OpName, OpDecorate, and various cases
of control-flow instructions such as OpBranch, OpPhi,
and OpFunctionCall.

TODO: Use CFG analysis for SSA checks.  In particular,
an ID defined inside a function body is only usable inside
that function body.  Also, use dominator info to catch
some failing cases.

Also:
* Validator test cases use (standard) assignment form.
* Update style to more closely follow the Google C++ style guide
* Remove color-diagnostics flag.
  This is enabled by default on terminals with color. Prints
  hidden ASCII for terminals that can't handle color(Emacs)
* Pass functors to SSAPass to check if the
  operand can be forward referenced based on its index value
* Return SPV_ERROR_INVALID_ID for ID related errors
  spvBinaryParse returned SPV_ERROR_INVALID_BINARY for all types of
  errors. Since spvBinaryParse does some ID validation, this was
  returning inappropriate error codes for some tests.
* Common fixture for validation tests.
  It only runs certian validation passes.
* Add a SPV_VALIDATE_SSA_BIT for testing purposes
* Fixtures now return error codes
* Add OpName support in diag message and unit tests
* Binary parsing can fail with invalid ID or invalid binary error code

Tests include:
* OpDecorate
* OpName
* OpMemberName
* OpBranchConditional
* OpSelectionMerge
* OpMemberDecorate
* OpGroupDecorate
* OpDeviceEnqueue
* Enable several tests failing in ID validation.
