	* symbols.h (snapshot_symbol): First parameter is now pointer
	to pointer to symbolS.
	* symbols.c (snapshot_symbol): Likewise. Store resulting symbol
	there. Use symbol_equated_p.
	* expr.c (resolve_expression): Change first argument to
	snapshot_symbol. Track possibly changed add_symbol consistently
	across function. Resolve more special cases with known result.
	Also update final_val when replacing add_symbol.

	* gas/all/cond.s: Also check .if works on equates to undefined
	when the expression value can be known without knowing the
	value of the symbol.
	* gas/all/cond.l: Adjust.
	* gas/i386/equ.s: Also check .if works on (equates to)
	registers when the expression value can be known without
	knowing the value of the register.
	* gas/i386/equ.e: Adjust.
