* tree-sra.c (instantiate_element): Use BYTES_BIG_ENDIAN for
bit-field layout.
(sra_build_assignment): Likewise. Set up mask depending on
precision, not type.
(sra_build_bf_assignment): Use BYTES_BIG_ENDIAN. Don't overflow
computing bit masks.
(sra_build_elt_assignment): Don't view-convert from signed to
unsigned.
(sra_explode_bitfield_assignment): Use bit-field type if
possible. Use BYTES_BIG_ENDIAN.
