David Neto 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).
