[Marek Polacek <polacek at redhat dot com>]

This patch is a cleanup of tests in gcc.dg/debug/ directory.
See https://gcc.gnu.org/ml/gcc-patches/2014-09/msg02656.html for more info.

Tested on x86_64-linux: vanilla results == results with this patch ==
results with this patch and gnu11 as a default.

Applying to trunk.

	* gcc.dg/debug/20010207-1.c: Use -fgnu89-inline.  Fix implicit
	declarations.
	* gcc.dg/debug/dwarf2-2.c: Fix defaulting to int.
	* gcc.dg/debug/dwarf2/ipa-cp1.c: Likewise.
	* gcc.dg/debug/pr42767.c: Likewise.
	* gcc.dg/debug/dwarf2/dwarf-die3.c: Use -fgnu89-inline.
	* gcc.dg/debug/dwarf2/inline1.c: Likewise.
	* gcc.dg/debug/dwarf2/inline2.c: Likewise.
	* gcc.dg/debug/pr49522.c: Fix implicit declarations.
