* Fix endianness of string literals To get correct and consistent encoding and decoding of string literals on big-endian platforms, use spvtools::utils::MakeString and MakeVector (or wrapper functions) consistently for handling string literals. - add variant of MakeVector that encodes a string literal into an existing vector of words - add variants of MakeString - add a wrapper spvDecodeLiteralStringOperand in source/ - fix wrapper Operand::AsString to use MakeString (source/opt) - remove Operand::AsCString as broken and unused - add a variant of GetOperandAs for string literals (source/val) ... and apply those wrappers throughout the code. Fixes #149 * Extend round trip test for StringLiterals to flip word order In the encoding/decoding roundtrip tests for string literals, include a case that flips byte order in words after encoding and then checks for successful decoding. That is, on a little-endian host flip to big-endian byte order and then decode, and vice versa. * BinaryParseTest.InstructionWithStringOperand: also flip byte order Test binary parsing of string operands both with the host's and with the reversed byte order.
