[Bug target/19357] New: ICE when long double argument arrives in general register

[jbeulich at novell dot com]

struct f {
	float f[8];
};

void ftest(struct f arg1, long double arg2) {
}

causes

movxf.c: In function `ftest':
movxf.c:5: error: insn does not satisfy its constraints:
(insn 46 34 66 0 (set (reg:XF 134 f6)
        (reg:XF 116 r36 [ arg2 ])) 26 {*movxf_internal} (nil)
    (expr_list:REG_DEAD (reg:XF 116 r36 [ arg2 ])
        (nil)))
movxf.c:5: internal compiler error: in final_scan_insn, at final.c:2359


This is appearantly due to only the fr->gr case being handled in the movxf expander.
