Scale down long-running tree-prof.exp tests for non-FDO testing.

2020-07-21  Sandra Loosemore  <sandra@codesourcery.com>

gcc/testsuite/
	* lib/profopt.exp (auto-profopt-execute): Pass -DFOR_AUTOFDO_TESTING
	on command line for both compiles.
	* gcc.dg/tree-prof/cold_partition_label.c: Scale down for
	non-FDO testing.
	* gcc.dg/tree-prof/crossmodule-indir-call-topn-1.c: Likewise.
	* gcc.dg/tree-prof/crossmodule-indir-call-topn-2.c: Likewise.
	* gcc.dg/tree-prof/indir-call-prof-topn.c: Likewise.
	* gcc.dg/tree-prof/section-attr-1.c: Likewise.
	* gcc.dg/tree-prof/section-attr-2.c: Likewise.
	* gcc.dg/tree-prof/section-attr-3.c: Likewise.
