tree-sra.c (struct access): Rename total_scalarization to grp_total_scalarization

2011-06-30  Martin Jambor  <mjambor@suse.cz>

	* tree-sra.c (struct access): Rename total_scalarization to
	grp_total_scalarization
	(completely_scalarize_var): New function.
	(sort_and_splice_var_accesses): Set total_scalarization in the
	representative access.
	(analyze_access_subtree): Propagate total scalarization accross the
	tree, no holes in totally scalarized trees, simplify coverage
	computation.
	(analyze_all_variable_accesses): Call completely_scalarize_var instead
	of completely_scalarize_record.

	* testsuite/gcc.dg/tree-ssa/sra-12.c: New test.
