Hi!

I forgot to decrement the counter, but given that nobody has hit it
until now it is possible that no frontend leaves RANGE_EXPR indexes in
CONSTRUCTORs around till late.  varasm.c seems to handle them though,
so fixed thusly, committed to trunk as obvious.

	PR debug/49262
	* dwarf2out.c (native_encode_initializer): Decrement count in each
	iteration.
