Change libspirv to spvtools namespace (#1678)
This CL changes all of the libspirv namespace code to spvtools to match
the rest of the code base.

[val] Add extra context to error messages. (#1600)
[val] Add extra context to error messages.

This CL extends the error messages produced by the validator to output the
disassembly of the errored line.

The validation_id messages have also been updated to print the line number of
the error instead of the word number. Note, the error number is from the start
of the SPIR-V, it does not include any headers printed in the disassembled code.

Fixes #670, #1581

83228137e1 Re-format source tree - NFC.
Re-formatted the source tree with the command:

$ /usr/bin/clang-format -style=file -i \
    $(find include source tools test utils -name '*.cpp' -or -name '*.h')

This required a fix to source/val/decoration.h.  It was not including
spirv.h, which broke builds when the #include headers were re-ordered by
clang-format.

d2938e4842 Re-format files in source, source/opt, source/util, source/val and tools.
NFC. This just makes sure every file is formatted following the
formatting definition in .clang-format.

Re-formatted with:

$ clang-format -i $(find source tools include -name '*.cpp')
$ clang-format -i $(find source tools include -name '*.h')

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.

6032b98c53 Change the interface for getWord().
* It's redundant to provide two mutable spv_position to getWord().
* getWord() should take string pointer by the style guide.

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.

4ddb431b16 Fixed internal compiler error in gcc-4.9.
This showed up in mips and mips64 builds. A combination of templates
and the error reporting were causing gcc to crash. This splits up the
functionality in a way that now successfully compiles.

9e545d7968 Assembler supports hex float constants.
The bit pattern for a hex float is preserved through
assembly and disassembly.

You can use a hex float to express Inf and any kind of NaN
in a portable way.

bae8851111 DiagnosticStream keeps a copy of the position.
Don't store the pointer, as the underlying storage
could disappear.  This a bit more flexible and robust.

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 {} \;

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.

51013d15ee SPV_FAILED_MATCH error mutes DiagnosticStream.
The DiagnosticStream will not emit the accumulated message
text if the error is SPV_FAILED_MATCH.

Change various interfaces to accept the intended error
code instead of a boolean "is_optional".  This allows
us to avoid repeating the following type of logic deep
inside helper methods:

  if (is_optional) return SPV_FAILED_MATCH;
  return diagnostic() << " message text ";

ac508b0d80 DiagnosticStream can convert to a stored error code
Use this to shorten error return code in the assembler.

For example, change this:

   if (error = something()) {
      diagnostic() << " Bad integer literal " << value;
      return SPV_ERROR_INVALID_VALUE;
   }

to this:

   if (error = something())
      return diagnostic() << " Bad integer literal " << value;

Also shorten code due to the fact that binaryEncodeU32 and
binaryCodeU64 can't fail (short of failure to expand a std::vector).

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.

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.

to every single function. This is in preparation for adding
id tracking.
