d02f68ae79 Update to 1.0 Rev 2 work-in-progress headers
Updated readme.

Note: The header advertises itself as Rev 1, but contains
many (all?) the updates intended for Rev 2.  We might need
to update one more time before SPIR-V 1.0 Rev2 is published.

Regenerated syntax tables for 1.0.

Changed names:
  InputTriangles -> Triangles
  InputQuads -> Quads
  InputIsolines -> Isolines
  WorkgroupLocal -> Workgroup
  WorkgroupGlobal -> CrossWorkgroup
  PrivateGlobal -> Private
  (Dim) InputTarget -> SubpassData
  WorkgroupLocalMemoryMask -> WorkgroupMemoryMask
  WorkgroupGlobalMemoryMask -> CrossWorkgroupMemoryMask
  AsyncGroupCopy -> GroupAsyncCopy
  WaitGroupEvents -> GroupWaitEvents

Remove:
  IndependentForwardProgress capability
  Smooth decoration
  FragColor BuiltIn
  WorkgroupLinearId in favour of LocalInvocationId
  ImageSRGBWrite capability
  Special OpenCL image instructions

Add:
  image channel data type UnormInt101010_2
  AcquireReleaseMask

InputTargetIndex updates:
  InputTargetIndex -> InputAttachmentIndex
  InputAttachmentIndex depends on InputAttachment capability,
  and it takes a literal number argument.

Capability StorageImageExtendedFormats updates:
  Enum value changed from 26 to 49. (Changes position in tables).
  Replaces AdvancedImageFormat capability.

OpenCL source language -> OpenCL_C, OpenCL_CPP

df920ecb71 Remove table parameters from API functions.
Opcode, operand, and external instruction tables are no longer
passed in as parameters to spvTextToBinary(), spvBinaryToText(),
and spvValidate().

229b90f6f4 Print OpConstant values according to type.
Zero and normal floating point values are printed with enough
enough digits to reproduce all the bits exactly.
Other float values (subnormal, infinity, and NaN) are printed
as hex floats.

Fix a binary parse bug: Count partially filled words in a
typed literal number operand.

TODO: Assembler support for hex numbers, and therefore reading
infinities and NaNs.

0ca6b59bfd Refactor the binary parser.
The binary parser has a C API, described in binary.h.
Eventually we will make it public in libspirv.h.
The API is event-driven in the sense that a callback is called
when a valid header is parsed, and for each parsed instruction.

Classify some operand types as "concrete".  The binary parser uses
only concrete operand types to describe parsed instructions.

The old disassembler APIs are moved into disassemble.cpp

TODO: Add unit tests for spvBinaryParse.

1a0334edee Run clang-format to enforce Google style globally.
Note that we are more strict than Google style for one aspect:
pointer/reference indicators are adjacent to their types, not
their variables.

b36e704a47 Use spirv.h instead of spirv.hpp.
This is a part of the effort to make libspirv.h C-compatible.

157e41bf57 Added type tracking to the disassembler.
TODO: Actually use the tracked types to make sure that we print out
values correctly.

537e77663d Added tracking to types and validated certain instructions.
We need to know how to generate correct SPIRV for cases like
OpConstant %int64 42 since the current parser will encode the 42 as a
32-bit value incorrectly.

This change is the first of a pair. This one tracks types, and makes
sure that OpConstant and OpSpecConstant are only ever called with
Integer or Float types, and OpSwitch is only called with integer
generating values.

13804e5d63 All values now represent symbolic names instead of mixed with numeric.
Also removed un-necessary heap-allocation of spv_named_id_table.
This removed the necessity to expose a function to create/destroy it
and simplified the interface.

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.

43f0e819c4 Avoid undefined pointer given to spvTextDestroy
The undefined pointer might get through to the call
to spvTextDestroy if the test fails on an earlier step.
In that case I just want to see the test failure, and
not a test failure followed by undefined behaviour.

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

c9a23a6fd5 Add binary-to-text test for single instruction
This is easier to debug!

Binary-to-text testing needs more tests, and more
specific tests.  That's for future work.

abafd5e674 Only use '%' as variable name prefix.
Since now we can distinguish between def and use according to
the variable's location, there is no need to keep two variable
prefixes.

Also reformat tests to use the value generating instruction
format ("<result-id> = <opcode> <operand>..").
