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.

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.

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.

find . -name "*.h" -exec clang-format -i {} \;
find . -name "*.cpp" -exec clang-format -i {} \;

9f79d789ec Inclusion guards follow Google C++ style
Follow the scheme in
http://google-styleguide.googlecode.com/svn/trunk/cppguide.html#The__define_Guard
except:
 - 'include/' is dropped from the guard token
 - 'source/' is dropped from the guard token

0b9816813b Hide spvBinaryHeaderSet with its only client.
Also rename it to SetHeader since it's not part of the "binary"
API.

ccc210b4cc Some minor clean-ups to binary.{h,cpp}.
Removed spvBinaryDecodeOpcode and spvBinaryDecodeOperand from the public
interface since they were only ever used in binary.cpp.

Replaced the usage of spv_operand_table_t and it's ilk with the
AssemblyGrammar to reduce the number of passed parameters.

Fixed typo in comment.

b5dc8fcd5d Support strings with up to 65535 chars, and null.
Move the definition of spv_instruction_t to an internal
header file, since it now depends on C++ and is not
used by the external interface.

Use a std::vector<uint32_t> in spv_instruction_t
instead of a fixed size array.

71fc05587b Refactored dynamic and static state out of text processing.
This reduces the number of arguments required to be passed
to every single function. This is in preparation for adding
id tracking.

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.

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

83e5a29b06 Code drop of the Codeplay spirv-tools source.
This commit contains the source for the SPIRV static library, spirv-as,
spirv-dis, and spirv-val tools.
