eopXD 10da9844d0 [LSR] Drop LSR solution if it is less profitable than baseline ... The LSR may suggest less profitable transformation to the loop. This patch adds check to prevent LSR from generating worse code than what we already have. Since LSR affects nearly all targets, the patch is guarded by the option 'lsr-drop-solution' and default as disable for now. The next step should be extending an TTI interface to allow target(s) to enable this enhancememnt. Debug log is added to remind user of such choice to skip the LSR solution.
