pa.c (move_operand): Relax "mode" test. 

Wed Jul 24 10:53:38 1996  Jeffrey A Law  (law@cygnus.com)

        * pa/pa.c (move_operand): Relax "mode" test.  Allow scaled
        indexed addressing modes.
        (output_fp_move_double): Tweak output strings to work with updated
        'F' and 'M' output modifiers.
        (print_operand): Collapse 'F' and 'M' into a single hunk of code.
        For auto-increment modes output "s,ma" and "s,mb".
        For scaled indexing modes output "x,s"
        For other addresses, output nothing for 'M' and "s" for 'F'.
        * pa.h (EXTRA_CONSTRAINT): Don't accept scaled indexed addresses
        for 'Q' and 'T'.  Do accept scaled indexed addresses for 'R'.
        (GO_IF_LEGITIMATE_ADDRESS): Accept scaled indexed addresses
        for SFmode and DFmode.
        * pa.md: Remove all scaled indexed load patterns.
        (movsi patterns): Accept scaled indexed addresses in some
        cases.  Update output strings for updated 'M' and 'F' output modifiers.
        (movhi, movqi, movsf, movdf, movdi patterns): Likewise.

;; This variant of the above insn can occur if the second operand

;; seem to be a way around it. Only recognize it while reloading.
;; Note how operand 3 uses a predicate of "const_int_operand", but
;; has constraints allowing a register. I don't know how this works,
;; but it somehow makes sure that out-of-range constants are placed
;; in a register which somehow magically is a "const_int_operand".
;; (this was stolen from alpha.md, I'm not going to try and change it.
;; Ugh. Output is a FP register; so we need to earlyclobber something
;; else as a temporary.
