lib/libm/arch/aarch64/fenv.c: revision 1.6
Fix fesetenv and feupdateenv.
- fesetenv is supposed to set the stored rounding mode (and stored trap
settings, but they have no effect on any ARMv8 I know).
- feupdateenv is supposed to re-raise the exceptions that were raised
in the environment when it was called.
XXX atf test
XXX pullup-9
Fix feraiseexcept.
- Don't touch the trap flags (though on all ARMv8 I know they have no
effect anyway).
- Don't clear any existing raised exception flags; just add to them.

When hardware subnormal support is available, disable flush-to-zero.

Similarly, when hardware NaN propagation is available, disable
default-NaN substitution.
This enables IEEE 754 semantics on any hardware that supports it by

Disable x87 implementations of sin, cos, tan.

The x87 hardware uses a bad approximation to pi for argument
reduction, and consequently yields bad answers for inputs near pi or

from the correct answer on the doubly rounded input.

Disable sanitizers for libm and librt
...
The sanitizers are designed to use pristine OS versions of these libraries,
install interceptors for public symbols in them and link with them in every
sanitized executable.
Having unmodified base libraries (c, m, rt, pthread) also makes the system
usable with programs linking with them and without sanitization, as there
are no fatal issues during the resolving of missing symbols.
The remaining libraries like libutil, libintl etc are prebuilt with
sanitization and all their users in the MKSANITIZER=yes distribution are
required to use the same sanitizer.
libc and libpthread are already marked with the NOSANITIZER flag.

Fix signed overflow in atan2
...
As a component of atan2(y, x), the case of x == 1.0 is farmed out to
atan(y). The current implementation of this comparison is vulnerable
to signed integer underflow (that is, undefined behavior), and it's
performed in a somewhat more complicated way than it need be. Change
it to not be quite so cute, rather directly comparing the high/low
bits of x to the specific IEEE-754 bit pattern that encodes 1.0.
