[flang] Modifications to ieee floating point environment procedures (#121949)
Intrinsic module procedures ieee_get_modes, ieee_set_modes, ieee_get_status, and ieee_set_status store and retrieve opaque data values whose size varies by machine and OS environment. These data values are usually, but not always small. Their sizes are not directly known in a cross compilation environment. Address this issue by implementing two mechanisms for processing these data values. Environments that use typical small data sizes can access storage defined at compile time. When this is not valid, data storage of any size can be allocated at runtime.
