x86_64: Use __seg_fs qualifiers in NPTL accessors
Use __seg_fs named address space qualifiers to cast NPTL accessors
to %fs: prefixed addresses. Use volatile access only where
strictly necessary.
Use existing assembly RSEQ_* accessors for x32 to
work around the GCC bug:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=121613
because negative value in __rseq_offset is used
as an offset from %fs.
