Richard Henderson 8443effb50 target-alpha: Split up FPCR value into separate fields. 
The fpcr_exc_status, fpcr_exc_mask, and fpcr_dyn_round fields
are stored in <softfloat.h> format for convenience during
regular execution.

Revert the addition of float_exception_mask to float_status,
added in ba0e276db4.

Richard Henderson ba0e276db4 target-alpha: Fixes for alpha-linux syscalls. 
1. Add correct definitions of error numbers.
2. Implement SYS_osf_sigprocmask
3. Implement SYS_osf_get/setsysinfo for IEEE_FP_CONTROL.

This last requires exposing the FPCR value to do_syscall.
Since this value is actually split up into the float_status,
expose routines from helper.c to access it.

Finally, also add a float_exception_mask field to float_status.
We don't actually use it to control delivery of exceptions to
the emulator yet, but simply hold the value that we placed there
when loading/storing the FPCR.
