    RA: Use simple LRA for huge functions

    The PR108500 test contains a huge function and RA spends a lot of time
    to compile the test with -O0.  The patch decreases compilation time
    considerably for huge functions.  Compilation time for the PR test
    decreases from 1235s to 709s on Intel i7-13600K.

            PR tree-optimization/108500

    gcc/ChangeLog:

            * params.opt (ira-simple-lra-insn-threshold): Add new param.
            * ira.cc (ira): Use the param to switch on simple LRA.=
