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.
