middle-end/84407 - honor -frounding-math for int to float conversion
This makes us honor -frounding-math for integer to float conversions
and avoid constant folding when such conversion is not exact.

* fold-const.c (fold_convert_const): Avoid int to float
constant folding with -frounding-math and inexact result.
* simplify-rtx.c (simplify_const_unary_operation): Likewise
for both float and unsigned_float.
* gcc.dg/torture/fp-uint64-convert-double-1.c: New testcase.
* gcc.dg/torture/fp-uint64-convert-double-2.c: Likewise.
