Fix warnings in build with G++

[Eric Botcazou <ebotcazou at adacore dot com>]

G++ kindly suggested making the following changes during a build so here we go.

Bootstrapped/regtested on x86_64-suse-linux, applied as obvious.


2011-07-12  Eric Botcazou  <ebotcazou@adacore.com>

	* cse.c (insert_with_costs): Put semi-colon after empty loop body
	on the next line.
	* emit-rtl.c (push_to_sequence): Likewise.
	* haifa-sched.c (max_issue): Likewise.
	* matrix-reorg.c (add_allocation_site): Likewise.
	* postreload-gcse.c (eliminate_partially_redundant_load): Likewise.
	* reload.c (alternative_allows_const_pool_ref): Likewise.
	* sched-rgn.c (rgn_add_block): Likewise.
	(rgn_fix_recovery_cfg): Likewise.
	* tree.c (attribute_list_contained): Likewise.
c-family/
	* c-ada-spec.c (dump_nested_types): Put semi-colon after empty loop
	body on the next line.
