    ifcvt: Fix bitpos calculation in bitfield lowering [PR107229]

    The bitposition calculation for the bitfield lowering in loop if conversion
was
    not taking DECL_FIELD_OFFSET into account, which meant that it would result
in
    wrong bitpositions for bitfields that did not end up having representations
    starting at the beginning of the struct.

    gcc/ChangeLog:

            PR tree-optimization/107229
