* signal.c (rb_sigaltstack_size): new. calculate stack size for
sigsegv handler. enlarge value when x86 or x86_64 on Linux.
Linux has very small MINSIGSTKSZ size (2048 bytes) and
our sigsegv routine need 5KiB at least. [Bug #7141]
* internal.h: add declaration of rb_sigaltstack_size().
* vm_core.h: remove ALT_STACK_SIZE definition.
* signal.c (rb_register_sigaltstack): replace ALT_STACK_SIZE with
rb_sigaltstack_size();
* gc.c (Init_heap): ditto.
* vm.c (th_init): ditto.
