xtensa: fix ICE on pr59037.c test
xtensa gcc gets ICE on pr59037.c test because its xtensa_output_literal
function cannot handle integer literals of sizes other than 4 and 8,
whereas the test uses 16-byte int vector.
Split integer literal formatting into the recursive function
xtensa_output_integer_literal_parts capable of handling literals of any
power of 2 size not less than 4.
