[PATCH 1/2] Remove pst from dwarf_decode_lines_1

[Yao Qi <yao@codesourcery.com>]

Hi,
Parameter 'pst' of function dwarf_decode_lines_1 isn't used except
to compute decode_for_pst_p, which has been got in the caller
dwarf_decode_lines.  I wonder it would be good if we just pass
'decode_for_pst_p'.

gdb:

	* dwarf2read.c (dwarf_decode_lines_1): Remove parameter 'pst'.
	Add parameter 'decode_for_pst_p'.  Callers update.
