4c21571728 Rename endian.h to spirv_endian.h
If we later add a source/ as an -I include directory,
then avoid confusing other headers that want to include the
standard "endian.h" from /usr/include.

Also rename source/endian.cpp to source/spirv_endian.cpp

* 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.

39fa148234 OpDecorate should not accept any number of literal operands.
This is a grammar fix.  The Decoration operand of OpDecorate (and
OpMemberDecorate) determines the remaining operands.  Don't just
allow any number of literal numbers as operands.

(The OperandVariableLiterals operand class as the last member
of the OpDecorate and OpMemberDecorate entries in in opcode.inc is
an artifact of how the spec generates the opcode descriptions. It's
not suitable for parsing those instructions.)

36909c05a5 binary parse test: extra words after string literal
Covers the case where the string literal is the
last operand.

TODO: Case where one more operand is expected after
the string literal.  Occurs only for the LinkageAttributes
decoration.  To test that, we need to update the grammar
as well.

292acb5b41 Don't add -frtti for tests. Use newer googletest.
Using -frtti caused link failures when both of the following are
in effect:
	-DDISABLE_EXCEPTIONS=ON
	-DDISABLE_RTTI=ON

The correct fix is to use tip-of-tree googletest.
Specifically, we need a version of googletest with the fix in
https://github.com/google/googletest/pull/612
In particular, it must be later than googletest 1.7.0.

up that fix, add -frtti for the the test executable only.

d9ad050a95 spvBinaryParse: fix overruns, handle image format
Add unit tests for all diagnostics issued by spvBinaryParse.

Handle image format operands in the binary parser and the
disassembler.

Document that the callback function pointers can be null,
in which case they are ignored.

Detect exhaustion of input when parsing an operand,
to avoid buffer overruns on some invalid input cases.

Fix the description strings for some operand types.
Make the diagnostic messages for those operand types
consistent between the assembler and binary parser.

ee8a007810 Clarify the non-SPV_SUCCESS case parser callbacks.
When a callback returns something other than SPV_SUCCESS,
then no futher callbacks are issued (parsing terminates early),
and no additional diagnostics are emitted.

The unit tests already check this behaviour.

750f205b63 Several unit tests for spvBinaryParse
Add a non-zero spv_result_t value SPV_REQUESTED_TERMINATION
which should be used to signal an ok result, but signals
early termination for a process, such as binary parsing.

Tests include:
 - correct contents sent to header and instruction callbacks
 - non-zero status from a callback should terminate parsing,
   but the parser should not generate its own diagnostic.

TODO: Check diagnostics generated by the parser itself.

7bff3eb6f9 spv_parsed_instruction_t cleanup
Add members:
 - words: a pointer to an array of words in the instruction,
   in host native endianness.
 - num_words: sizes the words member

Remove member:
 - offset

This simplifies clients of spvBinaryParse, because they don't
have to handle endianness translation.

Also, it makes the binary parse API more composable, allowing
for easy chaining of binary parse clients.  A binary parse client
is handed the array of words directly instead of having to reference
some external array of all the words in the SPIR-V binary.  It also
allows a binary parse client to mutate the instruction stream before
handing off to a downstream consumer.

3958c90277 Updated spirv.h header. Fixes SPV_VERSION macro
The SPV_VERSION macro value was updated to be 0x10000.
Previously it was missing the "0x" prefix, which caused
confusion.

The value of the const unsigned int SpvVersion has always
been 0x00010000.  That's what should appear as the version
word in the SPIR-V header.

The SPV_VERSION symbol is to be used in preprocessor directives.

14b93e49ed Generator word now has two 16-bit components
The high 16-bits are a registered generator tool.
These are registered at
https://www.khronos.org/registry/spir-v/api/spir-v.xml

The low 16-bits are tool-specific.  It might be a version number,
for example, but is not constrained by the spec or by the registration
process.

The disassembler prints the tool name when we know it.
If we don't, print "Unknown" and then the numeric tool number
in parentheses.
In all cases, the disassembler prints lower 16-bit number on the
same line but after the tool name.

Also add newly registered generators:

  7: Khronos SPIR-V Tools Assembler
