* gc.c (stack_end_address): new function to obtain stack end address.
stack_end_address calls __builtin_frame_address(0) to obtain the frame pointer of a stack frame of stack_end_address. The address is the stack pointer of the caller's stack frame. (SET_STACK_END): use stack_end_address. This makes the conservative garbage collector to scan a stack frame of the garbage_collect function itself. This is required because callee-save registers may be stored in the frame. [ruby-dev:25158] git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/branches/ruby_1_8@7546 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
