* cygtls.cc (san::leave/x86_64): Implement.
* cygtls.h (class tls_pathbuf): Move counter variables into a union.
Add 64 bit element _counters covering both counter variables to
optimize save and restore operations.
(class san/x86_64): Only store single 64 bit value.
(san::san/x86_64): Implement.
(san::leave/x86_64): Only declare here, as returns_twice function.
Explain why.
(class san/i686): Change type of _c_cnt and _w_cnt to uint32_t.
(__try/x86_64): Move definition of __sebastian after the first memory
barrier. Drop __sebastian.setup call.
