bb-reorder: Fix assertion

When touching bb-reorder yesterday, I've noticed the checking assert
doesn't actually check what it meant to.
Because asm_noperands returns >= 0 for inline asm patterns (in that case
number of input+output+label operands, so asm goto has at least one)
and -1 if it isn't inline asm.

The following patch fixes the assertion to actually check that it is
asm goto.

	* bb-reorder.cc (fix_up_fall_thru_edges): Fix up checking assert,
	asm_noperands < 0 means it is not asm goto too.
