Transfers control to a function starting with a new stack.

EntryPoint must never return.
Transfers control to the function specified by EntryPoint using the
new stack specified by NewStack and passing in the parameters specified
by Context1 and Context2. Context1 and Context2 are optional and may
be NULL. The function EntryPoint must never return. This function
supports a variable number of arguments following the NewStack parameter.
These additional arguments are ignored on IA-32, x64, and EBC.
IPF CPUs expect one additional parameter of type VOID * that specifies
the new backing store pointer.
If EntryPoint is NULL, then ASSERT().
If NewStack is NULL, then ASSERT().
For IPF CPUs, if NewStack is not aligned on a 16-byte boundary, then ASSERT().
@param EntryPoint A pointer to function to call with the new stack.
@param Context1 A pointer to the context to pass into the EntryPoint
