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.
