[lldb] Partly revert 370734: Test 'frame select -r' and fix that INT32_MIN breaks the option parser
This somehow caused that 'frame select X' ends up being interpreted as 'frame select -r 1' when 'up' or 'down'
were run before 'frame select X'. See rdar://55791276.
Partly reverting to unbreak master. The changes that aren't reverted are the generic 'frame select -r' tests
that are obviously NFC and test existing behavior.
