[Dexter] Collate penalties of the same type into a single line for each

Currently in Dexter, every step at which a DexExpectWatchValue/Type does
not have the correct value is printed on a separate line. This patch
reduces the size of the text output by instead printing each incorrect
result (i.e. each incorrect value seen, 'Variable optimized out', and so
on) on its own line, alongside a list of the steps at which that result
was seen. This makes for much less spam in the output when watches are
missing or wrong for many steps.
