[libc] Add implementations of nextafter[f|l] functions.

2021-01-06T06:32:39+00:00

A differential fuzzer for these functions has also been added.
Along the way, a small correction has been done to the normal/subnormal
limits of x86 long double values.

[libc] Add implementations of nearbyint[f|l].

2021-01-06T05:51:10+00:00

The implementation is exactly the same as rint* as even rint does not
raise any floating point exceptions currently. [Note that the standards
do not specify that floating point exceptions must be raised - they
leave it up to the implementation to choose to raise FE_INEXACT when
rounding non-integral values.]

[libc] Switch functions to using global headers

2020-11-21T00:07:17+00:00

This switches all of the files in src/string, src/math, and
test/src/math from using relative paths (e.g. `#include “include/string.h”`)
to global paths (e.g. `#include `) to make bringing up those
functions on other platforms, such as fuchsia, easier.

to round to nearest. Also, a bug in NormalFloat to subnormal number
conversion has been fixed.
