Log:
[builtins] Implement __floattitf() & __floatuntitf()
Implement the missing __floattitf() and __floatuntitf() functions, to
convert 128-bit (unsigned) integers to quad-precision floating-point
types. This is needed e.g. on AArch64 where 'long double' is
a quad-precision type.
The code is based on the existing code for __floattixf()
and __floatuntixf(), updated to account for different bit field lengths
of quad-precision float. The tests are also copied, with the rounding
tests adjusted for longer significand.
