* First cut at cleaning up PA instruction parsing.

	* config/tc-hppa.c (pa_get_absolute_expression): Accept pointer to
	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.

        * write.c (fixup_segment): Delete {SEG,GLOBAL}_DIFF_ALLOWED code,
        it was PA specific and is no longer needed (it's now handled 
        within the PA backend).
