Ding-Kai Chen 66192aa129 xtensa: add HW FPU sequences for DIV/SQRT/RECIP/RSQRT 
Use new FPU instruction sequences documented in the ISA book to
implement __divsf3, __divdf3, __recipsf2, __recipdf2, __rsqrtsf2,
__rsqrtdf2 and __ieee754_sqrtf and __ieee754_sqrt.

Max Filippov 9bfcbdeecf xtensa: fix libgcc build with --text-section-literals 
Functions __muldf3_aux, __divdf3_aux, __mulsf3_aux and __divsf3_aux
don't start with leaf_entry, so they need explicit .literal_position,
otherwise libgcc build fails in the presence of --text-section-literals.

libgcc/
	* config/xtensa/ieee754-df.S (__muldf3_aux, __divdf3_aux): Add
	.literal_position before the function.
	* config/xtensa/ieee754-sf.S (__mulsf3_aux, __divsf3_aux):
	Likewise.
