Fix the method for getting the stack pointer in Win64 ABI.

The generated ceCaptureCStackPointers must account for the 32 bytes reserved for saving the 4 register parameters which are allocated whatever the real number of parameters.

Item was changed:
  ----- Method: CogX64Compiler>>leafCallStackPointerDelta (in category 'abi') -----
  leafCallStackPointerDelta
  	"Answer the delta from the stack pointer after a call to the stack pointer
  	 immediately prior to the call.  This is used to compute the stack pointer
  	 immediately prior to  call from within a leaf routine, which in turn is used
+ 	 to capture the c stack pointer to use in trampolines back into the C run-time.
+ 	In Win64 ABI, also count the stack reserved for saving 4 register arguments."
