[PATCH] Don't change stack_alignment_needed for __tls_get_addr

[H.J. Lu]

__tls_get_addr must be called with 16-byte aligned stack, which is
guaranted by setting preferred_stack_boundary to 128 bits.  There
is no need to change stack_alignment_needed for __tls_get_addr.

Tested on x86-64.  OK for trunk?
