Unnecessary code in Power-function about 4klang

[gopher-atz]

You are right, that's a leftover from the very first version of 4klang where a generic power function was called with the base provided by the caller.
Same applies to the comments.

It should be safe to modify it, as you already said.
I'll update the repo, once i checked all the recent incoming comments/bugs.

Thanks for the hint!

P.S:
The original function looked like this:

; //----------------------------------------------------------------------------------------
; //	Power function
; //----------------------------------------------------------------------------------------
; //	Input :		st0		:	base
; //			st1		:	exponent
; //	Output:		st0		:	result
; //----------------------------------------------------------------------------------------
go4kPower:				; // base			exp
	fyl2x				; // log2_base		-
	fld	st0			; // log2_base		log2_base
	frndint				; // (int)log2_base	log2_base
	fxch				; // log2_base		(int)log2_base
	fsub	st0, st1		; // (frac)log2_base	(int)log2_base
	f2xm1				; // 2 ^ '' -	1		(int)log2_base
	fld1				; // 1				2 ^ '' -	1		(int)log2_base
	faddp	st1, st0		; // 2 ^ ''			(int)log2_base
	fscale			
	fstp	st1
	ret
