Eliminate data race reported by TSan in GC_have_errors

* alloc.c (GC_gcollect): Replace read of GC_have_errors with
get_have_errors() call.
* malloc.c (GC_generic_malloc): Likewise.
* mallocx.c (GC_generic_malloc_ignore_off_page,
GC_generic_malloc_many): Likewise.
* reclaim.c (GC_print_all_errors): Likewise.
* dbg_mlc.c [!SHORT_DBG_HDRS] (GC_debug_free, GC_add_smashed): Replace
GC_have_errors=TRUE with GC_SET_HAVE_ERRORS().
* reclaim.c (GC_add_leaked): Likewise.
* include/private/gc_priv.h [AO_HAVE_store] (GC_have_errors): Change
type from GC_bool to volatile AO_t; refine comment.
* reclaim.c [AO_HAVE_store] (GC_have_errors): Likewise.
* include/private/gc_priv.h (GC_SET_HAVE_ERRORS, get_have_errors):
Define macro.
