Add new constant data structure.
This patch provides the data structure and function to convert a
CONST_INT, CONST_DOUBLE, CONST_VECTOR, or VEC_DUPLICATE of a constant) to
an array of bytes, half-words, words, and double words that can be loaded
into a 128-bit vector register.
The next patches will use this data structure to generate code that
generates load of the vector/floating point registers using the XXSPLTIDP,
XXSPLTIW, and LXVKQ instructions that were added in power10.
