Use alias linkage and visibility to decide tls access mode.
This matches both what we do for the non-thread case and what gcc does.
With this patch clang would match gcc's behaviour in
static __thread int a = 42;
extern __thread int b __attribute__((alias("a")));
int *f(void) { return &a; }
int *g(void) { return &b; }
if not for pr19843. Manually writing the IL does produce the same access modes.
It is also a step in the direction of fixing pr19844.
