Log:
Don't change stack_alignment_needed for __tls_get_addr

__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.

        PR target/68986
        * config/i386/i386.c (ix86_update_stack_boundary): Don't
        change stack_alignment_needed for __tls_get_addr call.
