  [GlobalMerge] Fix handling of const options

For the NewPM, the merge-const option was assigned to an unused
option field. Assign it to the correct one. The merge-const-aggressive
option was not supported -- and invalid options were silently ignored.
Accept it and error on invalid options.

For the LegacyPM, the corresponding cl::opt options were ignored when
called via opt rather than llc.
