[PR118017][LRA]: Don't inherit reg of non-uniform reg class
In the PR case LRA inherited value of register of class INT_SSE_REGS
which resulted in LRA cycling when LRA tried to use different move
alternatives with SSE/general regs and memory. The patch rejects to
inherit such (non-uniform) classes to prevent cycling.
gcc/ChangeLog:
PR target/118017
* lra-constraints.cc (inherit_reload_reg): Check reg class on uniformity.
gcc/testsuite/ChangeLog:
PR target/118017
* gcc.target/i386/pr118017.c: New.
