vxworks.h (DBX_REGISTER_NUMBER): Pick distinct map for 64bits.

* config/i386/vxworks.h (DBX_REGISTER_NUMBER): Pick distinct
map for 64bits.
(TARGET_OS_CPP_BUILTINS): builtin_define CPU to X86_64 for 64bit
targets. Pick a default if no particular attempt applied.
(STACK_CHECK_PROTECT): Double for 64bit targets, which have
larger contexts.
