4ac601a2c3 libspirv.h doesn't depend on spirv_operands.hpp anymore.
Also change spirv_operands.hpp to a C header since we only have
an enum inside it, and move it to source/.

55ecc2e097 Fixed warnings on windows and constness of spv_binary.
Replaced uint64_t with size_t in the places that make sense and
added spv_const_binary{,_t} to allow the interface to accept non
modifiable spirv where appropriate.

201caf7001 spv_operand_type_t cleanup.
- Concrete operand types are never optional.
  Split them to make this so, e.g. add SPV_OPERAND_TYPE_IMAGE
  since there was SPV_OPERAND_TYPE_OPTIONAL_IMAGE.
  Similarly for SPV_OPERAND_TYPE_MEMORY_ACCESS.
  This entails duplicating two operand table entries.

- The above, plus some rearranging of enums, allows us to define
  first and last optional operand types, and first and last
  variable operand types.
  This lets us simplify the code for spvOperandIsOptional, and
  spvOperandIsVariable.

- Replace SPV_OPERAND_TYPE_MULTIWORD_LITERAL_NUMBER with the
  more accurately named SPV_OPERAND_TYPE_TYPED_LITERAL_NUMBER.
  Its special characteristic is that the type of the literal
  number is determined by some previous operand in the instruction.
  This is used for literals in OpSwitch, OpConstant, and OpSpecConstant.
  This lets us refactor operand parsing cases in the assembler.

- Remove the special required-thing-in-optional-tuple in favour of
  the corresponding concrete operand type:
        SPV_OPERAND_TYPE_ID_IN_OPTIONAL_TUPLE
    --> SPV_OPERAND_TYPE_ID
        SPV_OPERAND_TYPE_INTEGER_LITERAL_IN_OPTIONAL_TUPLE
    --> SPV_OPERAND_TYPE_INTEGER_LITERAL

- Constrain spvOpeandTypeStr to only have to work for non-variable
  operand types.  Add a test for this.

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.

Note that we are more strict than Google style for one aspect:
pointer/reference indicators are adjacent to their types, not
their variables.

445ce4401d Add operand type for extension instruction number
This is required to support extended instructions that
have literal numbers as operands.  An example is OpenCL's
vloadn.

The previous code in the assembler assumed that *any* literal
number argument in any part of an OpExtInst must be the name
of the extended instruction.  That's true only for the first
literal number argument.

21c4ad4b22 Add OpenCL extended instructions.
Versions 1.2, 2.0, and 2.1 all use the same
extended instruction list.

Updated the source code patch for the SPIR-V doc generator,
so it can both generate the core syntax table, and also the
OpenCL extended instructions table.

Tested the Math and Common functions.
TODO: test the remaining entries.

6483bd7132 Enforce suitable literal number operands to be unsigned integers.
Except for OpConstant and OpSpecConstant, all other literal number
operands are indeed unsigned integers. So,

* Rename all *LITERAL_NUMBER* operand types to *LITERAL_INTEGER*.
* Expect unsigned integers for *LITERAL_INTEGER* operands.
* Keep MULITPLE_WORD_LITERAL untouched since it is only used by
  OpConstant and OpSpecConstant.

And we want to provide the capability to specify floating-point
numbers after !<integer> in the alternate parsing mode. So,
OPTIONAL_LITERAL_NUMBER is reserved for OPTIONAL_CIV.

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.

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.
