Remove source/message.h (#1838)
The code in source/message was only used in a single set of tests to
format the output results. This CL changes the test to verify the
message instead of all the error values and removes the source/message
code.

59de6100b5 Add asm, dis support for DebugInfo extended instruction set
Add grammar file for DebugInfo extended instruction set
- Each new operand enum kind in extinst.debuginfo.grammar.json maps
  to a new value in spv_operand_type_t.
- Add new concrete enum operand types for DebugInfo

Generate a C header for the DebugInfo extended instruction set

Add table lookup of DebugInfo extended instrutions

Handle the debug info operand types in binary parser,
disassembler, and assembler.

Add DebugInfo round trip tests for assembler, disassembler

Android.mk: Support DebugInfo extended instruction set

The extinst.debuginfo.grammar.json file is currently part of
SPIRV-Tools source.

It contributes operand type enums, so it has to be processed
along with the core grammar files.

We also generate a C header DebugInfo.h.

Add necessary grammar file processing to Android.mk.

755f97f534 Add a callback mechanism for communicating messages to callers.
Every time an event happens in the library that the user should be
aware of, the callback will be invoked.

The existing diagnostic mechanism is hijacked internally by a
callback that creates an diagnostic object each time an event
happens.

1773b95737 Pull out the number parsing logic
Pull out the number parsing logic from
AssemblyContext::binaryEncodeNumericLiteral() to utilities.

The new utility function: `ParseAndEncodeNumber()` now accepts:
  * number text to parse
  * number type
  * a emit function, which is a function which will be called with each
    parsed uint32 word.
  * a pointer to std::string to be overwritten with error messages.
    (pass nullptr if expect no error message)
and returns:
  * an enum result type to indicate the status

Type/Structs moved to utility:
  * template<typename T> class ClampToZeroIfUnsignedType

New type:
* enum EncodeNumberStatus: success or error code
* NumberType: hold the number type information for the number to be parsed.
 * several helper functions are also added for NumberType.

Functions moved to utility:
  * Helpers:
    * template<typename T> checkRangeAndIfHexThenSignExtend() -> CheckRangeAndIfHex....()
  * Interfaces:
    * template<typename T> parseNumber() -> ParseNumber()
    * binaryEncodeIntegerLiteral() -> ParseAndEncodeIntegerNumber()
    * binaryEncodeFloatingPointLiteral() -> ParseAndEncodeFloatingPointNumber()
    * binaryEncodeNumericLiteral() -> ParseAndEncodeNumber()

Tests added/moved to test/ParseNumber.cpp, including tests for:
* ParseNumber(): This is moved from TextToBinary.cpp to ParseNumber.cpp
* ParseAndEncodeIntegerNumber(): New added
* ParseAndEncodeFloatingPointNumber(): New added
* ParseAndEncodeNumber(): New added

Note that the error messages are kept almost the same as before, but
they may be inappropriate for an utility function. Those will be fixed
in another CL.

5a70335bf1 Rearrange headers
Now we have public headers arranged as follows:
$SPIRV_TOOLS_ROOT/include/spirv-tools/libspirv.h
$SPIRV_TOOLS_ROOT/include/spirv/spirv.h
$SPIRV_TOOLS_ROOT/include/spirv/GLSL.std.450.h
$SPIRV_TOOLS_ROOT/include/spirv/OpenCL.std.h

A project should use -I$SPIRV_TOOLS_ROOT/include
and then #include "spirv-tools/libspirv.h"

The headers from the SPIR-V Registry can be accessed as "spirv/spirv."
for example.

The install target should also install the headers from the SPIR-V
Registry.  The libspirv.h header is broken otherwise.

The SPIRV-Tools library depends on the headers from the SPIR-V Registry.

The util/bitutils.h and util/hex_float.h are pulled into the internal
source tree.  Those are not part of the public API to SPIRV-Tools.

2889a0c21c Use syntax tables for SPIR-V 1.0 Rev3
- The SPIR-V spec generator has changed how it represents optional
  operands.  Now it tracks a separate boolean flag indicating optionality.
  However, SPIRV-Tools still wants to represent both operand class
  and optionality in the same enums space (SPV_OPERAND_TYPE_*).
  So there's extra work in the patch.

- In the spec generator, OperandImage is now OperandImageOperands.
  This affects enum translation in opcode.cpp.

- In the spec generator, image operands are explicitly followed by
  Id, and VariableIds.  However, SPIRV-Tools uses the bits set
  in the image operand bitmask to control the number and meaning
  of the Ids that follow.  So in writing the opcode.inc syntax
  table, drop all operands after OperandImageOperands.

- Some enums are now more explicitly represented in the generated
  opcode.inc:
    - AccessQualifier (e.g. on OpTypeImage), in both required and
      optional flavours.
    - MemoryAccess (e.g. on loads and stores)

- Add SPV_OPERAND_TYPE_OPTIONAL_ACCESS_QUALIFIER

- Add tests for the optional AccessQualifier operand on OpTypeImage.

- Update the AccessQualifier test for OpTypeImage so it's a round
  trip test through the disassembler as well.

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.

Bits 16-23: SPIR-V major number (1)

Bits   0-7: SPIR-V minor number (2)

and the disassemble will print it in major.minor.revision form.

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

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.

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.

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.
