6fa3f8aad9 Remove dependency on SPIR-V headers in libspirv.h.
For fulfilling this purpose, the |opcode| field in the
|spv_parsed_instruction_t| struct is changed to of type uint16_t.

Also add functions to query the information of a given SPIR-V
target environment.

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.

8ddd4ec102 Bottom byte of version header word should be 0
The assembler should always make it 0.
The disassembler should ignore it.

Remove the macro support for supplying a value for it.

3d348a8440 The version header word has 3 byte-size components.
Bits 24-31: 0
Bits 16-23: SPIR-V major number (1)
Bits  8-15: SPIR-V minor number (0)
Bits   0-7: SPIR-V minor number (2)

The assembler will construct the word appropriately,
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:
  6: Khronos LLVM/SPIR-V Translator
  7: Khronos SPIR-V Tools Assembler
