re PR tree-optimization/91257 (Compile-time and memory-hog hog)

2019-07-29  Richard Biener  <rguenther@suse.de>

PR tree-optimization/91257
* tree-vrp.c (operand_less_p): Avoid dispatching to fold for
most cases, instead call compare_values which handles the
symbolic ranges we handle specially.
(compare_values_warnv): Do not call operand_less_p but open-code
the effective fold calls.  Avoid converting so much.
