[builtins] [arm] Combine pushes in GenerateTailCallToReturnedCode

Combines several individual pushes/pops into a single call to Push in
GenerateTailCallToReturnedCode. This saves a single instruction since
pushes in descending register order can be be merged into a single
instruction. The pop merge doesn't save anything but is done for
consistency.
