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
