561dc4e975 Remove SPV_OPERAND_TYPE_LITERAL
All uses of OptionalLiteral by the SPIR-V spec are used
for literal numbers.

Also rename:
- SPV_OPERAND_TYPE_OPTIONAL_LITERAL to
  SPV_OPERAND_TYPE_OPTIONAL_LITERAL_NUMBER.
- SPV_OPERAND_TYPE_VARIABLE_LITERAL to
  SPV_OPERAND_TYPE_VARIABLE_LITERAL_NUMBER.
- SPV_OPERAND_TYPE_VARIABLE_LITERAL_ID to
  SPV_OPERAND_TYPE_VARIABLE_LITERAL_NUMBER_ID.
- SPV_OPERAND_TYPE_VARIABLE_ID_LITERAL to
  SPV_OPERAND_TYPE_VARIABLE_ID_LITERAL_NUMBER.
- SPV_OPERAND_TYPE_LITERAL_IN_OPTIONAL_TUPLE to
  SPV_OPERAND_TYPE_LITERAL_NUMBER_IN_OPTIONAL_TUPLE.

dbaf40718a Update to Rev32 headers. Part 1.
Just enough fixes to code make it build and pass tests.

Core changes:
 - Fix spelling for: NoPerspective, NonWritable, NonReadable,
 - Remove NoStaticUse, RelaxedMask

GLSL changes:
 - Fixed spelling for: InverseSqrt, FaceForward, MatrixInverse,
   SmoothStep, FindILsb, FindSMsb, FindUMsb
 - Replace Mix with IMix and FMix
 - Remove AddCarry, SubBorrow, MulExtended

Replace header OpenCLLib.h with OpenCL.std.h

TODO:
 - Regenerate the core instruction syntax table (source/opcode.inc)
 - Add test coverage for new enums and instructions.

ee1b3bb3bb Assembler support for image operands from Rev31
Rev32 and later add many more image operands, and
rearrange their values.

3fca4cddee Remove SPV_OPERAND_TYPE_VARIABLE_MEMORY_ACCESS
If a memory mask operand is present, it is a mask.  The mask appears
only once, so just use SPV_OPERAND_TYPE_OPTIONAL_MEMORY_MASK.

The "variable literals" aspect comes into play as follows: if the
Aligned bit is set in the mask, then the parser will be made to
expect the alignment value as a literal number operand that follows
the mask.  That is done through mask operand expansion.

b30a0c529b Assembler test for Dim, ImageFormat enums.
Adds SPV_OPERAND_TYPE_SAMPLER_IMAGE_FORMAT, and the
translation tables for its values from the spv::ImageFormat values.

b41d150b7f Support multiple word literal numbers as constants.
Add a new operand type SPV_OPERAND_TYPE_MULTIWORD_LITERAL_NUMBER
to represent those operands that can expand into multiple words.
Now only OpConstant and OpSpecConstant have such kind of operand.

4005670363 Limit the use of spvCheck and spvCheckReturn to validator.
spvCheck is indeed just an if-statement. Defining such a macro
doesn't help much.

06efdc59e1 Add an API parameter to choose assembly syntax format for assembler.
Added a new enum for supported assembly syntax formats:
Canonical Assembly Format (CAF) and Assignment Assembly Format (AAF).

Updated assembler interface functions to support choice of assembly
syntax format.

cfeac48a37 Removed the ambiguity in the API for cleaning input vs output data.
Previous the api used spv_text_t and spv_binary_t for both input
and output, but depending on the usage, you either MUST
call spvBinaryDestroy or you MUST NOT call spvBinaryDestroy on the
pointer.

78c3b43774 Use opcode operand definitions from SPIR-V specification generator.
The assembler and disassembler now use a dynamically adjusted
sequence of expected operand types.  (Internally, it is a deque,
for readability.)  Both parsers repeatedly pull an expected operand
type from the left of this pattern list, and try to match the next
input token against it.

The expected pattern is adjusted during the parse to accommodate:
- an extended instruction's expected operands, depending on the
  extended instruction's index.
- when an operand itself has operands
- to handle sequences of zero or more operands, or pairs of
  operands.  These are expanded lazily during the parse.

Adds spv::OperandClass from the SPIR-V specification generator.

Modifies spv_operand_desc_t:
 - adds hasResult, hasType, and operandClass array to the opcode
description type.
 - "wordCount" is replaced with "numTypes", which counts the number
   of entries in operandTypes.  And each of those describes a
   *logical* operand, including the type id for the instruction,
   and the result id for the instruction.  A logical operand could be
   variable-width, such as a literal string.

Adds opcode.inc, an automatically-generated table of operation
descriptions, with one line to describe each core instruction.
Externally, we have modified the SPIR-V spec doc generator to
emit this file.
(We have hacked this copy to use the old semantics for OpLine.)

Inside the assembler, parsing an operand may fail with new
error code SPV_FAIL_MATCH.  For an optional operand, this is not
fatal, but should trigger backtracking at a higher level.

The spvTextIsStartOfNewInst checks the case of the third letter
of what might be an opcode.  So now, "OpenCL" does not look like
an opcode name.

In assembly, the EntryPoint name field is mandatory, but can be
an empty string.

Adjust tests for changes to:
- OpSampedImage
- OpTypeSampler
