PPC: [strong] Check arity of functions

PPC: [strong] Check arity of functions

Port 3226e980200035f37c86fef4b11fb307e17764a2

Original commit message:
In strong mode it is an error to call a function with too few
arguments.

This is enforced inside the ArgumentsAdaptorTrampoline.

This does not yet handle rest parameters

Late, drive-by comment:

Can you avoid ifdef here by using SharedFunctionInfo::kStrongModeBitWithinByte
as x64 & ia32 (and now mips64) do? Implies also changing load to lbz(r7,
FieldMemOperand(r7, SharedFunctionInfo::kStrongModeByteOffset));

Makes sense.  I'll look at doing this in a future CL.
