Ah, yes; those are specifically testing for the aliases that we can't 
generate on darwin.  I'll add dg-require-alias to those tests.  Thanks 
for the testing.

Recompiling the testcase with -fextern-tls-init doesn't produce the missing 
_ZTH1i.

Hmm, compiling with -fextern-tls-init should give an error for you. 
Doesn't it?
