This silences tons of -Wformat= warnings when building ARC Linux kernel

The test defines int bitfields that are more than 16 bits wide, and this
fails for the avr with its 16 bit integer size. Therefore, require

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.

With the SPE ABI, if we wrap GPRs we need to handle the upper half of the
extended 64-bit registers as well, which we cannot easily do. So, this
patch disables separate shrink-wrapping for the SPE ABI.

The add expander still contains some expansion code that was required for the
previous prolog/epilog code, but which is no longer needed. I also noticed

codesize improvements.
