Do not scan static roots pages unless dirty if SOFT_VDB (Linux)
Issue #265 (bdwgc).
* include/private/gc_priv.h (GC_push_conditional_static): Declare (as
a macro or function).
* include/private/gcconfig.h [!PROC_VDB && !NO_VDB_FOR_STATIC_ROOTS]
(NO_VDB_FOR_STATIC_ROOTS): Do not define if SOFT_VDB.
* mark.c [!GC_DISABLE_INCREMENTAL && !NO_VDB_FOR_STATIC_ROOTS
&& !PROC_VDB] (GC_static_page_was_dirty): New STATIC function.
* mark.c [!GC_DISABLE_INCREMENTAL && !NO_VDB_FOR_STATIC_ROOTS]
(GC_push_conditional_static): New function (uses
GC_static_page_was_dirty unless PROC_VDB).
* mark_rts.c (GC_PUSH_CONDITIONAL_STATIC): Remove.
* mark_rts.c (GC_PUSH_CONDITIONAL): Use GC_push_conditional_static
instead of GC_PUSH_CONDITIONAL_STATIC.
* os_dep.c (SOFT_VDB): Update comment about implementation.
* os_dep.c [SOFT_VDB && CHECKSUMS] (GC_soft_read_dirty): Call
GC_or_pages() only unless output_unneeded, remove assertion about it.
* os_dep.c [SOFT_VDB && !NO_VDB_FOR_STATIC_ROOTS] (GC_soft_read_dirty):
Call soft_set_grungy_pages() for every element of GC_static_roots.
