erts/hipe: unbreak arity 4 BIFs
This fixes arity 4 BIF support in HiPE, following its introduction on master (OTP 18) via the nox/ets-update_counter-4 merge. - define standard_bif_interface_4, nbif_4_gc_after_bif, and nbif_4_simple_exception on ARM: unbreaks the build on ARM - remove bogus stack re-alignment from standard_bif_interface_4 on AMD64: for 4-arg BIFs the stack is already aligned, and the code would misalign the C stack which violates the ABI and may cause alignment faults in vectorized code - the nbif_4_simple_exception OPD name on PPC64 was incorrectly using the nbif_3_simple_exception OPD name: this would have caused a multiple definition error in the assembler or linker In addition there are a few cleanups: - fix standard_bif_interface_N comment on x86 - fix standard_bif_interface_4 comment on SPARC - separate nbif_N_simple_exception blocks by empty lines on PPC, like on ARM, to clearly show which things belong together - fix standard_bif_interface_N comment on ARM - fix standard_bif_interface_4 on AMD64 to match the indentation and spacing conventions of the rest of that file
