clean up FP exception code in sys_float.c
This performs a number of cleanups in the FP exception code: - inline the body of unmask_fpe_conditional() in its only caller, then delete the duplicated and identical definitions of it - start the big processor-specific block with a comment describing the two functions that must be defined, then delete redundant comments at all the mask_*() functions - add a comment before fpe_sig_action() explaining exactly what processor-specific action is required of it - flatten #ifdef nesting in fpe_sig_action() - move common code in the x86 unmask_fpe() and erts_restore_fpu() function into a subroutine - minor tweaks: drop a redundant L suffix on a 0, add a comment after an #else, bump the size of a debug buffer, There should be no change in behaviour from these changes.
