[X86] Use StackArgTokenFactor for all stores when setting up tail calls. (#126244)

Before this patch, the stack argument token factor was used if any
outgoing stack slots needed to be written, but not when writing the
return address to a stack slot. Writing the return address stack slot
can also alias a stack slot for an input argument.

Always use StackArgumentTokenFactor, to ensure the store of the return
address will always use it, i.e. happen after all input arguments are
loaded.
