    • Add out-of-line versions of some <stdatomic.h> functions (PR c/65083). · c29c36ad 
      PR c/65083 notes that some functions in <stdatomic.h> are normal
functions, not generic functions, and so need to have out-of-line
copies that can be called when macro expansion is suppressed (unlike
the generic functions where DR#419 makes it undefined if you suppress
a macro expansion).

This patch adds such out-of-line definitions in libatomic for those
six functions, at a new LIBATOMIC_1.2 symbol version, as trivial
wrappers to the <stdatomic.h> macros, along with declarations of those
functions in <stdatomic.h>.  Tests are added that are based on the
corresponding tests for the macros, but with parentheses around the
function names to force the out-of-line functions to be used.

Bootstrapped with no regressions on x86_64-pc-linux-gnu.

gcc:
	* ginclude/stdatomic.h (atomic_thread_fence, atomic_signal_fence)
	(atomic_flag_test_and_set, atomic_flag_test_and_set_explicit)
	(atomic_flag_clear, atomic_flag_clear_explicit): Declare as
	functions before defining as macros.

gcc/testsuite:
	* gcc.dg/atomic/stdatomic-fence-2.c,
	gcc.dg/atomic/stdatomic-flag-2.c: New tests.

libatomic:
	* fence.c, flag.c: New files.
	* Makefile.am (libatomic_la_SOURCES): Add fence.c and flag.c.
	* Makefile.in: Regenerate.
	* configure.ac (libtool_VERSION): Change to 3:0:2.
	* configure: Regenerate.
	* libatomic.map (LIBATOMIC_1.2): New symbol version.

    • Enable condegen in case of cond phis. · 21c7259c 
      The codegen of conditional PHIs inside the scop where one predecessor dominates
the other was difficult so it wasn't enabled in the previous patch. After a
couple of bug-fixes this has been enabled in this patch.  Not all the cases
could be handled in this case because it becomes difficult to map the basic
block back to original code in some cases.

Bug-fixes:
1. The vec_find returns -1 when no element was found. This wasn't checked.
2. When the arguments to pending phis could not be resolved in the second pass,
the codegen would fail so the new code should be cleaned up.

This patch passes regtest and bootstrap on linux-x86-64 with
BOOT_CFLAGS='-O2 -fgraphite-identity -floop-nest-optimize'
