Convert some evrp uses in DOM to the range_query API.
DOM is the last remaining user of the evrp engine. This patch converts a few uses of the engine and vr-values into the new API. There is one subtle change. The call to vr_value's op_with_constant_singleton_value_range can theoretically return non-constants, unlike the range_query API which only returns constants. In this particular case it doesn't matter because the symbolic stuff will have been handled by the const_and_copies/avail_exprs read in the SSA_NAME_VALUE copy immediately before. I have verified this is the case by asserting that all calls to op_with_constant_singleton_value_range at this point return either NULL or an INTEGER_CST. Tested on x86-64 Linux with a regstrap, as well as the aforementioned assert. gcc/ChangeLog: * gimple-ssa-evrp-analyze.h (class evrp_range_analyzer): Remove vrp_visit_cond_stmt. * tree-ssa-dom.c (cprop_operand): Convert to range_query API. (cprop_into_stmt): Same. (dom_opt_dom_walker::optimize_stmt): Same.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
