bitint: Handle m_bitfld_load cast in outer m_cast_conditional [PR114555]
We ICE on the following testcase, because we use result of a PHI node
which is only conditional because of a m_cast_conditional on the outermost
loops PHI node argument and so is invalid SSA form.
The following patch fixes it like similar cases elsewhere by adding
needed intervening PHI(s).
