[dev.cc] cmd/6a, etc: fix line number accounting during #ifdef

Browse Source 
Lines beginning with #ifdef, #else, #endif were not incrementing
the line number, resulting in bad line number information for
assembly files with #ifdefs.

Example:

	#ifndef GOARCH_ppc64
	#endif
	#ifdef GOARCH_ppc64le
	#endif

	TEXT ·use(SB),7,$0
		RET

Before this change, the line number recorded for use in 6a -S output
(and in the runtime information in the binary) was 4 too low.
