[Bug target/27566] [4.1/4.2 Regression] ICEs in final_scan_insn and reload_cse_simplify_operands for vectors with SPE

[pinskia at gcc dot gnu dot org]

We have before reload:
(insn 45 44 46 3 (set (reg:V4HI 131 [ D.1754 ])
        (const_vector:V4HI [
                (const_int 0 [0x0])
                (const_int 0 [0x0])
                (const_int 0 [0x0])
                (const_int 0 [0x0])
            ])) 933 {*movv4hi_internal} (nil)
    (nil))

Which then gets turned into:
(insn 73 44 45 3 (set (reg:SI 10 10)
        (high:SI (symbol_ref/u:SI ("*.LC0") [flags 0x2]))) 319 {elf_high} (nil)
    (nil))

(insn 45 73 74 3 (set (reg:V4HI 0 0 [orig:131 D.1754 ] [131])
        (mem/u/c/i:V4HI (lo_sum:SI (reg:SI 10 10) 
                (symbol_ref/u:SI ("*.LC0") [flags 0x2])) [0 S8 A64])) 933
{*movv4hi_internal} (nil)
    (nil))
Which is normally fine except for the fact V4HI memory only accepts reg+reg and
not reg+imm.
