re PR rtl-optimization/80747 (gcc.dg/tree-ssa/tailrecursion-4.c fails with ICE when compiled with options "-fprofile-use -freorder-blocks-and-partition")
PR rtl-optimization/80747
PR rtl-optimization/83512
* cfgrtl.c (force_nonfallthru_and_redirect): When splitting
succ edge from ENTRY, copy partition from e->dest to the newly
created bb.
* bb-reorder.c (reorder_basic_blocks_simple): If last_tail is
ENTRY, use BB_PARTITION of its successor block as current_partition.
Don't copy partition when splitting succ edge from ENTRY.
* gcc.dg/pr80747.c: New test.
* gcc.dg/pr83512.c: New test.
