Replacelrint(3),lrintf(3),llrint(3) andllrintf(3) implementations withthe same implementation that we're already using forlrintl(3) andllrintl(3).The old implementations were derived from code from NetBSD that didn't passthe lib/libm/msun/lrint_test regress test.  NetBSD replaced theirimplementation with the FreeBSD implementation of this code which we werealready using forlrintl(3) andllrintl(3).  This fixes the regress test.ok bluhm@, millert@

Trick GCC optimizer into clipping any extra precision by making wvolatile;  a similar hack was already being used in lrintf().This will make rint and {,l}lrint family functions actually work;i.e. on m68k rintf(8.6F) was 8.625.

The {,l}lround{,f} implementations are based on {,l}lrint{,f},therefore affected by the same bugs I've fixed a week ago.The high part was being clipped for all exponents greater or equalto 52.  Fix this to use RESTYPE_BITS instead;  also make the codeconsistent.

The {,l}lrint{,f} functions avoid to shift results by more than 31bits, because "behavior is implementation defined in this case".However, this is wrong;  behavior is undefined if the right operandis greater than or equal to the width of the promoted left operand.This broke {,l}lrint{,f} (64-bit architectures), and llrint{,f}(32-bit architectures) where results are actually 64-bit values.The high part was clipped for all exponents greater or equal to 52.Fix this to use RESTYPE_BITS instead;  {,l}lrint{,f} are now ableto pass our regression tests, and I think are right now.

The assumption that |1.0 * 2^exp| = 0, exp < -1 cannot be made whenwe round towards -inf or +inf.

Move llrint.c, llrintf.c, lrint.c and lrintf.c to s_llrint.c, s_llrintf.c,s_lrint.c and s_lrintf.c, and add i387-specific assembler versions.ok deraadt@, otto@
