2ea54f5d1b Add tests for SubgroupDispatch.
Introduced in v1.1, SubgroupDispatch adds the following:
- two new execution modes
- one new capability
- two new opcodes

Extend ValidateBase methods to take a spv_target_env.  Replace the
context_ member with ScopedContext inside the said methods.  Give
ScopedContext wider visibility by moving it outside
TextToBinaryTestBase.

b6ccd0d891 Remove spv_validate_options_t and change tests accrodingly.
Users always want to run all the checks. The spv_validate_options_t
mechanism, which provides little benefits to users, complicates the
internal implementation and also makes the tests exercise different
paths as users do.

Right now the tests are more like integration tests instead of
unit tests, which should be our next refactoring aim.

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

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.
