533c0b6943 combine: Fix PR80233
If combine has added an unconditional trap there will be a new basic
block as well.  It will then end up considering the NOTE_INSN_BASIC_BLOCK
as the last_combined_insn, but then it tries to take the DF_INSN_LUID
of that and that dereferences a NULL pointer (since such a note is not
an INSN_P).

This fixes it by not taking non-insns as last_combined_insn.


	PR rtl-optimization/80233
	* combine.c (combine_instructions): Only take NONDEBUG_INSN_P insns
	as last_combined_insn.  Do not test for BARRIER_P separately.

0dee55fec9 [ARC] Define _REENTRANT when -pthread is passed.
The compiler is supposed to have the builtin defined _REENTRANT defined
when -pthread is passed, which wasn't done on the ARC architecture.

When _REENTRANT is not passed, the C library will not use reentrant
functions, and the latest version of ax_pthread.m4 from the
autoconf-archive will no longer detect that thread support is
available (see https://savannah.gnu.org/patch/?8186).
