RFA: patch to solve PR 48331 and PR 48334 in IRA

The following patch solves PR 48331 and PR 48334. The problem was in that allocno profitable hard regs were not set up for priority colouring and function assign_hard_reg used a garbage in its decisions generating wrong code or code of awful quality.

Is it ok to commit?
