[pr19844] Add thread local mode to aliases.
...
This matches gcc's behavior. It also seems natural given that aliases
contain other properties that govern how it is accessed (linkage,
visibility, dll storage).
Clang still has to be updated to expose this feature to C.

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.
