  [flang] Modifications to ieee_support_standard (#128895)

Some Arm processors support exception halting control and some do not.
An Arm executable will run on either type of processor, so it is
effectively unknown at compile time whether or not this support will be
available. ieee_support_halting is therefore implemented with a runtime
check.

The result of a call to ieee_support_standard depends in part on support
for halting control. Update the ieee_support_standard implementation to
check for support for halting control at runtime.
