* expr.h (get_bit_range): Declare.
* expr.c (get_bit_range): Export.
* fold-const.c (optimize_bit_field_compare): Use get_bit_range and
word_mode again to constrain the bitfield access.

* fold-const.c (optimize_bit_field_compare): Don't try to use
word_mode unconditionally for reading the bit field, look at
DECL_BIT_FIELD_REPRESENTATIVE instead.
* gcc.target/powerpc/pr71310.c: New testcase.
