insn structure as an argument, and a pointer to a string. All
callers changed. Always read any field selector here. Call
evaluate absolute to get a return value.
(evaluate_absolute): Addept pointer to insn structure as its
argument. All callers changed.
(INSERT_FIELD_AND_CONTINUE): New macro for inserting a bitfield
into an instruction and continuing the main pa_ip loop.
(CHECK_FIELD): New macro for simple range checking of fields.
(pa_ip): Delete unused variables. Use INSERT_FIELD_AND_CONTINUE
and CHECK_FIELD. All immediate fields now pass through
pa_get_absolute_expression which will also handle field selectors.
Delete dead code. Simplify.
(md_apply_fix_1): Use CHECK_FIELD to verify any fixes that are
applied are in range. Use bfd_put_32 rather than inserting each
byte of the fixed instrution into the buffer ourselves.

mean it is the one, some times a typedef class can have the same
memeber method and args. This probably will not happen with new
version of g++, but it does happen in old g++ and cause gdb error.
