middle-end/57245 - honor -frounding-math in real truncation
The following honors -frounding-math when converting a FP constant
to another FP type.

PR middle-end/57245
* fold-const.c (fold_convert_const_real_from_real): Honor
-frounding-math if the conversion is not exact.
* simplify-rtx.c (simplify_const_unary_operation): Do not
simplify FLOAT_TRUNCATE with sign dependent rounding.
* gcc.dg/torture/fp-double-convert-float-1.c: New testcase.
