Philip Reames 854a84c0b0 [LVI] Improve select handling to use condition 
This patches teaches LVI to recognize clamp idioms (e.g. select(a > 5, a, 5) will always produce something greater than 5.

The tests end up being somewhat simplistic because trying to exercise the case I actually care about (a loop with a range check on a clamped secondary induction variable) ends up tripping across a couple of other imprecisions in the analysis. Ah, the joys of LVI...

lldb Don't crash if we have a DIE that has a DW_AT_ranges attribute and yet the SymbolFileDWARF doesn't have a DebugRanges. If this happens print a nice error message to prompt the user to file a bug and attach the offending DWARF file so we can get the correct compiler fixed. 2016-02-12 00:07:16 +00:00
