letters defined.

s390_contiguous_bitmask_p, s390_symref_operand_p,
s390_check_symref_alignment, s390_reload_larl_operand,
s390_reload_symref_address): New functions.
(s390_branch_condition_mnemonic): Support compare and branch
instructions.
(s390_mem_constraint): Avoid symrefs to accepted by the 'T'
and 'W' constraints.

symbol refs or symbol refs to floating point or QI/TI mode
integer values.
(legitimate_address_p): Accept symbol references as addresses.
(s390_expand_insv): Use rotate and insert selected bits
instruction for insv when building for z10.
(print_operand_address): Handle symbol ref addresses.
(print_operand): Output modifier 'c' added for signed byte
values.
(s390_encode_section_info): Mark symbol refs with
SYMBOL_FLAG_NOT_NATURALLY_ALIGNED if appropriate.
