e6861a99f8 re PR driver/68463 (Offloading fails when some objects are compiled with LTO and some without)
gcc/
	PR driver/68463
	* config/gnu-user.h (CRTOFFLOADBEGIN): Define.  Add crtoffloadbegin.o if
	offloading is enabled and -fopenacc or -fopenmp is specified.
	(CRTOFFLOADEND): Likewise.
	(GNU_USER_TARGET_STARTFILE_SPEC): Add CRTOFFLOADBEGIN.
	(GNU_USER_TARGET_ENDFILE_SPEC): Add CRTOFFLOADEND.
	* lto-wrapper.c (offloadbegin, offloadend): Remove static vars.
	(offload_objects_file_name): New static var.
	(tool_cleanup): Remove offload_objects_file_name file.
	(find_offloadbeginend): Replace with ...
	(find_crtoffloadtable): ... this.
	(run_gcc): Remove offload_argc and offload_argv.
	Get offload_objects_file_name from -foffload-objects=... option.
	Read names of object files with offload from this file, pass them to
	compile_images_for_offload_targets.  Don't call find_offloadbeginend and
	don't pass offloadbegin and offloadend to the linker.  Don't pass
	offload non-LTO files to the linker, because now they're not claimed.

046957830e remove useless if-before-free tests
Change "if (E) free (E);" to "free (E);" everywhere except in the
libgo/, intl/, zlib/ and classpath/ directories.
Also transform equivalent variants like
"if (E != NULL) free (E);" and allow an extra cast on the
argument to free.  Otherwise, the tested and freed "E"
expressions must be identical, modulo white space.
