The test defines int bitfields that are more than 16 bits wide, and this

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
