[PATCH] sel-sched: Fix erroneous re-use of pointer to last insn in a BB (PR 48235)

[Steve Ellcey]

Vladimir and Dmitry,

The new test you added, gcc.dg/pr48235.c, is failing on IA64 because
it gets this excess message:

cc1: note: -freorder-blocks-and-partition does not work on this architecture

Could you modify the test to either filter out this message or not 
use the -freorder-blocks-and-partition option in IA64 or not run the
test at all on IA64.  I notice that gcc.dg/tree-prof/pr45354.c looks
like this test but also has:

/* { dg-require-effective-target freorder } */

That test does not fail, or run, on IA64 due to this dg option.
