Update lrint/lrintf/lrintl for x32
The x86_64 versions of lrint/lrintf/ lrintl are aliases for the long
long versions which isn't correct for x32, where exceptions must respect
overflow for 32-bit long.  Separate versions of the long functions for
x32 that convert to 32-bit long and raise the right exceptions for that
conversion, while keeping the aliases in the non-x32 case.

Tested on x86_64 and x32.  There are no code changes in libm.so on
x86_64.

	* sysdeps/x86_64/fpu/s_llrint.S (__lrint): Add alias only if
	__ILP32__ isn't defined.
	(lrint): Likewise.
	* sysdeps/x86_64/fpu/s_llrintf.S (__lrintf): Likewise.
	(lrintf): Likewise.
	* sysdeps/x86_64/fpu/s_llrintl.S (__lrintl): Likewise.
	(lrintl): Likewise.
	* sysdeps/x86_64/x32/fpu/s_lrint.S: New file.
