Starting with Solaris 11.4 (which is now the required minimal version), Solaris does
support __cxa_atexit. This patch reflects that.
One might consider removing the affected tests altogether instead of inverting them,
as is done on other targets.
Besides, this lets two ASan tests PASS:
AddressSanitizer-i386-sunos :: TestCases/init-order-atexit.cc
AddressSanitizer-i386-sunos-dynamic :: TestCases/init-order-atexit.cc
Tested on x86_64-pc-solaris2.11 and sparcv9-sun-solaris2.11.

"-fno-use-cxa-atexit" was a default provided by the initial
commit offering hexagon support. This is no longer required.

register destructor functions annotated with __attribute__((destructor))
using __cxa_atexit or atexit.
Register destructor functions annotated with __attribute__((destructor))
calling __cxa_atexit in a synthesized constructor function instead of
emitting references to the functions in a special section.
The primary reason for adding this option is that we are planning to
deprecate the __mod_term_funcs section on Darwin in the future. This
feature is enabled by default only on Darwin. Users who do not want this
can use command line option 'fno_register_global_dtors_with_atexit' to
disable it.

This primarily impacts the Windows MSVC and Windows itanium
environments. Windows MSVC does not use `__cxa_atexit` and Itanium
follows suit. Simplify the logic for the default value calculation and
blanket the Windows environments to default to off for use of
`__cxa_atexit`.
