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();
