StandardConversionSequence - represents a standard conversion sequence (C++ 13.3.3.1.1).
A standard conversion sequence contains between zero and three conversions. If a particular conversion is not needed, it will be set to the identity conversion (ICK_Identity). Note that the three conversions are specified as separate members (rather than in an array) so that we can keep the size of a standard conversion sequence to a single word.

| LLVM_DUMP_METHOD void StandardConversionSequence::dump | ( | ) | const |
dump - Print this standard conversion sequence to standard error.
